Ko te Polyvinyl Chloride (PVC) tētahi o ngā pūmua tino maha ngā whakamahinga me te whānui o te whakamahinga puta noa i te ao, e kitea ana ngā tono i roto i te hanga, te motuka, te takai, ngā taputapu hauora, me te tini ke atu o ngā ahumahi. Ko tōna rongonui i ahu mai i ōna āhuatanga miihini pai rawa atu, te ātete matū, te iti o te utu, me te ngāwari o te tukatuka. Heoi, he iti noa te herenga o te PVC: ko te kore pumau o te wera. Ina pāngia e te wera i te wā e tukatukahia ana (pēnei i te extrusion, te werohanga, te calendering rānei) te whakamahinga roa rānei i roto i ngā taiao pāmahana teitei, ka pirau te PVC, ka whakararu i tana mahi, tōna āhua, me tōna haumaru. Koinei te wāhi e whakamahia ai ngā whakaū wera PVC—e kiia ana koNgā whakaū wera PVC—he tūranga tino nui. Hei kaiārahiWhakapūmau PVCkaihanga me ngā tekau tau o te wheako,MATUA TOPJOYkua noho hei kaiārahi mō te whakawhanake i ngā whakaū mahi-teitei hei tiaki i ngā hua PVC puta noa i tō rātou huringa ora. I roto i tēnei tuhinga, ka rukuhia e mātou te pūtaiao kei muri i te pirau o te PVC, ka tūhuratia me pēheaNgā whakaū wera PVCte mahi i te wā e tukatuka ana, e whakamahana ana hoki, me te whakamārama i ngā whakaaro matua mō te whiriwhiri i te pūmau tika.
Te Pūtake: He aha te pirau o te PVC i raro i te wera
Hei mārama ki te mahi a ngā mea whakaū wera PVC, me mārama tuatahi he aha te take e ngawari ai te PVC ki te pirau wera. Ko te hanganga matū o te PVC he mea hanga mai i ngā waeine vinyl chloride (-CH₂-CHCl-), me ngā ngota chlorine e piri ana ki te mekameka polymer. Kāore ēnei ngota chlorine i te pumau ōrite—ko ētahi he "koretake" (he tauhohe matū) nā te hanganga rerekē o te mekameka, pērā i ngā hononga takirua whakamutunga, ngā pūwāhi peka, ngā poke rānei i whakaurua mai i te wā polymerization.
Ina werahia te PVC ki ngā pāmahana neke atu i te 100°C (he awhe noa mō te tukatuka, e hiahiatia ana te 160–200°C), ka tīmata he tukanga pirau tere-ake, ko te nuinga o te wā ko te tango i te waikura. Anei te wehewehenga taahiraa-i-te-taahiraa:
• TīmatangaKa motuhia e te pūngao wera te hononga i waenga i te ngota chlorine koretake me te waro tata, ka tukuna te hau hauwai chloride (HCl). Ka waiho he hononga takirua i roto i te mekameka polymer.
• Te whakatipuKa mahi te HCl i tukuna hei whakakorikori, ka whakaoho i tētahi tauhohenga mekameka ka tangohia atu ētahi atu ngota HCl mai i ngā wae tata. Ka hangaia he raupapatanga polyene honohono (ngā hononga takirua tauutuutu) i te mekameka polymer.
• WhakamutuKa pāngia ngā polyene honohono e ētahi atu tauhohenga, pērā i te haehae mekameka (te whatinga o te mekameka polymer) te hononga whakawhiti rānei (te hanganga o ngā hononga i waenga i ngā mekameka), ka ngaro ai ngā āhuatanga ā-pūkaha.
Ko ngā hua e kitea ana o tēnei pirau ko te rerekētanga o te tae (mai i te kōwhai ki te parauri ki te mangu, nā ngā polyenes honohono), te pakarukaru, te ngoikore o te kaha pānga, ā, ka pakaru pea te hua PVC. Mō ngā tono pēnei i te takai kai, ngā ngongo hauora, ngā taonga takaro a ngā tamariki rānei, ka taea hoki e te pirau te tuku i ngā hua taha kino, ka tūpono he mōrearea ki te hauora.
Me pēhea te whakaiti i te pirau e ngā whakau wera PVC
Ka mahi ngā whakaū wera PVC mā te whakakore i te huringa whakararu wera i tētahi, neke atu rānei ngā wāhanga. He rerekē ā rātou tikanga i runga i te hanganga matū, engari he rite tonu ngā whāinga matua: te aukati i te tukunga HCl, te whakakore i ngā rauropi kore utu, te whakaū i ngā ngota chlorine koretake, me te aukati i te hanganga polyene. Kei raro nei ngā tikanga mahi matua o ngā whakaū wera PVC, me ngā tirohanga mai i te tohungatanga whakawhanake hua o TOPJOY CHEMICAL.
▼ Te Whakakore i te Waikawa HCl
I te mea he whakakorikori te HCl mō te pirau haere, ko te tango (te whakakore) i te HCl kua tukuna tētahi o ngā mahi tino nui o ngā whakaū wera PVC. Ka tauhohe ngā whakakorikori me ngā āhuatanga taketake ki te HCl hei hanga i ngā matū kore-whakakorikori, ka mutu ai te wāhanga horapa.
Ko ngā tauira o ngā mea whakaū i te HCl ko ngā hopi whakarewa (hei tauira, te konupūmā stearate, te konutea stearate), ngā tote mata (hei tauira, te konutea stearate, te konutea sulfate mata tribasic), me ngā mea whakaū whakarewa whakauru (konutea-konutea, barium-konutea). I TOPJOY CHEMICAL, kua hangaia ā mātou mea whakaū konupūmā-konutea hei whakaū pai i te HCl me te tutuki i ngā paerewa taiao tino pakari—he rerekē ki ngā mea whakaū e ahu mai ana i te mata, e whakakorea ana puta noa i te ao nā runga i ngā āwangawanga paitini. Ka hangaia e ēnei mea whakaū konupūmā-konutea ngā pūhaumāota whakarewa me te waikawa stearic hei hua taha, ā, he kore paitini ēnei e rua, ā, he hototahi ki ngā matrices PVC.
▼ Te Whakapūmau i ngā Ngātome Haumāota e Noho Ora Ana
Ko tētahi atu tikanga matua ko te whakakapi i ngā ngota chlorine koretake ki ngā rōpū mahi pumau ake i mua i te tīmatanga o te tango i te waikura. Mā tēnei "taupoki" o ngā pae tauhohe ka ārai i te tīmatanga o te tukanga pirau.
He tino pai ngā kaiwhakaū orotini (hei tauira, te methyltin, te butyltin) ki tēnei mahi. Ka tauhohe rātou ki ngā ngota chlorine koretake hei hanga hononga waro-tine pumau, ka whakakore i te pūtake mō te tukunga HCl. He tino whai hua ēnei kaiwhakaū mō ngā tono PVC mahi-teitei, pērā i te pakari.Ngā paipa PVC, ngā kōtaha, me ngā kiriata mārama, he mea nui te pumau o te wera me te mārama o te whatu mō te wā roa. Ko ngā whakaū wera PVC organotin kounga teitei a TOPJOY CHEMICAL kua hangaia hei whakarato i te pumau tino pai i ngā horopeta iti, me te whakaiti i ngā utu rauemi me te pupuri tonu i te kounga o te hua.
▼ Hopu Pūwero Koreutu
Ka puta hoki i te pirau wera ngā rauropi kore utu (ngā momo tino tauhohe me ngā irahiko kore takirua) e tere ake ai te tapahi mekameka me te hononga whakawhiti. Ko ētahi o ngā mea whakaū wera PVC ka mahi hei kaihoroi rauropi kore utu, e whakakore ana i ēnei momo tauhohe hei whakamutu i te huringa pirau.
He maha ngā wā ka whakauruhia ngā antioxidants pēnei i te phenolics, te phosphites rānei ki roto i ngā ranunga stabilizer hei whakarei ake i te hopu i ngā rauropi kore utu. He maha ngā wā ka whakakotahihia e ngā otinga stabilizer ritenga a TOPJOY CHEMICAL ngā stabilizers tuatahi (hei tauira,konupūmā-konutea, organotin) me ngā antioxidants tuarua hei whakarato i te tiakitanga maha-paparanga, inā koa mō ngā hua PVC e pāngia ana e te wera me te hāora (te whakahekenga wera-waikura).
▼ Te aukati i te hanganga o te Polyene
Ko ngā polyene honohono te take o te tae kerekere me te pakarukaru o te PVC. Ka whakararu ētahi o ngā mea whakau i te hanganga o ēnei raupapatanga mā te tauhohe ki ngā hononga takirua i hangaia i te wā o te tango i te waikura, ka pakaru te honohono me te aukati i te whanaketanga tae atu.
He tino whai hua ngā whakapūmau whenua onge, he momo whakapūmau wera PVC hou, ki te aukati i te hanganga polyene. Ka hangaia he matatini ki te mekameka polymer, ka whakapūmau i ngā hononga takirua me te whakaiti i te tae o te tae. Hei kaihanga whakapūmau PVC matatau, kua haumi a TOPJOY CHEMICAL ki te R&D whakapūmau whenua onge hei whakatutuki i ngā ahumahi e hiahia ana ki te tae o te tae tino iti, pērā i ngā kōtaha matapihi PVC me ngā kiriata whakapaipai.
Ngā Momo Matua o ngā Whakapūmau Wera PVC me ā rātou Whakamahinga
Ka whakarōpūtia ngā whakaū wera PVC e ai ki te hanganga matū, ia ia he āhuatanga ahurei e tika ana mō ngā hanganga me ngā whakamahinga PVC motuhake. Kei raro nei he tirohanga whānui o ngā momo tino noa, me ngā tirohanga mai i ngā wheako ahumahi o TOPJOY CHEMICAL.
▼ Ngā Whakapūmau Konupūmā-Konutea (Ca-Zn)
Hei ngā mea whakaū taiao e whakamahia whānuitia ana,Ngā mea whakaū Ca-Znkei te whakakapi i ngā whakaū e ahu mai ana i te mata me te barium-cadmium nā te mea kāore e paitini, ā, e tutuki ana hoki i ngā ture o te ao (hei tauira, EU REACH, US FDA). Ka mahi rātou mā te whakakotahitanga o te tango HCl (konupūmā stearate) me te hopu i ngā rauropi kore utu (konutearate), me ngā pānga mahi tahi e whakarei ake ana i te pumau o te wera.
He whānuitanga o ngā momo e tukuna ana e TOPJOY CHEMICALNgā whakaū wera Ca-Zn PVChe mea hanga mō ngā momo whakamahinga rerekē: PVC mārō (ngā paipa, ngā kōtaha) me te PVC ngāwari (ngā taura, ngā ngongo, ngā taonga takaro). Ka tutuki ā mātou whakaū Ca-Zn kounga kai i ngā paerewa FDA, ā, he mea tino pai mō ngā takai PVC me ngā taputapu hauora.
▼ Ngā Whakaū Organotin
E mōhiotia ana ngā whakaū o te organotin mō tō rātou pumau wera, mārama, me te ātete ki te huarere. E whakamahia ana ēnei i roto i ngā hua PVC pakari e hiahia ana ki te mahi teitei, pērā i ngā kiriata mārama, ngā paipa mō te kawe wai wera, me ngā wāhanga motuka. Ko ngā whakaū methyltin te mea e pai ake ana mō te mārama, ko ngā whakaū butyltin ia e tuku ana i te ātete wera roa.
I TOPJOY CHEMICAL, ka hangaia e mātou he pūmau oro-tin parakore teitei e whakaiti ana i te hekenga (he mea nui mō te pa ki te kai) me te whakarato i te mahi ōrite puta noa i ngā pāmahana tukatuka rerekē.
▼ Ngā Whakapūmau Ārahi-Mata
Ngā mea whakaū i ahu mai i te matai mua ko te paerewa ahumahi nā te iti o te utu me te tino pumau o te wera. Heoi, nā te paitini o ēnei matū kua whānuitia te aukati i roto i a Ūropi, Amerika Te Raki, me te maha o ngā whenua Āhia. Kei te whakamahia tonutia ēnei matū i roto i ētahi tono iti te utu i roto i ngā mākete kāore i te whakahaeretia, engari e tautoko ana a TOPJOY CHEMICAL i ngā huarahi kē atu e pai ana ki te taiao, ā, kāore e hangaia ana ngā mea whakaū e ahu mai ana i te mata.
▼ Ngā Kaiwhakaū Whenua Onge
I ahu mai i ngā huānga whenua onge (hei tauira, te lanthanum, te cerium), ka tukuna e ēnei whakaū he pumau wera tino pai, he iti te tae o te tae, ā, he pai te hototahi ki te PVC. He pai mō ngā tono teitei pēnei i ngā kōtaha matapihi PVC, ngā pepa whakapaipai, me ngā wāhanga o roto o te motuka. Ka whakaratohia e te raupapa whakaū whenua onge a TOPJOY CHEMICAL he taurite o te mahi me te whai huatanga utu, ka waiho hei huarahi kē atu ki ngā whakaū organotin i roto i ētahi āhuatanga.
Ngā Whakapūmau Wera PVC i roto i te Tukatuka me te Whakamahinga Mutunga
Ehara i te mahi tukatuka anake te mahi a ngā mea whakaū wera PVC—e tiaki ana hoki i ngā hua PVC i te wā e whakamahia ana mō te wā roa i roto i ngā taiao pāmahana teitei. Me tūhuratia tā rātou mahi i ngā wāhanga e rua.
▼ I te wā e Tukatuka ana
Ko te tukatuka PVC ko te whakamahana i te pūmua ki ngā pāmahana rewa (160–200°C) hei hanga āhua. I ēnei pāmahana, ka tere te pirau me te kore he mea whakau - he maha ngā wā i roto i ngā meneti. Ka whakaroahia e ngā mea whakau wera PVC te "matapihi tukatuka," te wā e mau tonu ai ngā āhuatanga o te PVC, ā, ka taea te hanga āhua me te kore e pirau.
Hei tauira, i roto i te whakaputanga o ngā paipa PVC, ka whakarite ngā whakaū Ca-Zn mai i TOPJOY CHEMICAL kia mau tonu te matotoru me te kaha ā-ringa o te PVC rewa puta noa i te tukanga whakaputanga, ka ārai i ngā hapa o te mata (hei tauira, te rerekētanga o te tae, ngā kapiti) me te whakarite kia ōrite te rahi o ngā paipa. I roto i te whakahāngai werohanga o ngā taonga takaro PVC, ka ārai ngā whakaū iti-hekenga i ngā hua kino mai i te turuturu ki roto i te hua whakamutunga, ka tutuki ai ngā paerewa haumaru.
▼ I te wā e whakamahana ana mō te wā roa (Whakamahinga Mutunga)
He maha ngā hua PVC e pāngia ana e te wera roa i roto i ā rātou whakamahinga whakamutunga, pērā i ngā paipa wai wera, ngā wāhanga o raro o te waka, me ngā taura hiko. Me whakarato e ngā mea whakaū wera PVC he parenga mō te wā roa hei ārai i te pakaru wawe.
He tino whai hua ngā whakaū o te organotin me te whenua onge mō te pumau o te wera mō te wā roa. Hei tauira, ka whakamahia ngā whakaū butyltin a TOPJOY CHEMICAL i roto i ngā paipa wai wera PVC, kia mau tonu ai te kaha me te ātete matū o ngā paipa ahakoa ka pāngia e te wai 60–80°C mō ngā tekau tau. I roto i ngā taura hiko, ka tiakina e ā mātou whakaū Ca-Zn me ngā tāpiringa antioxidant te whakamarumaru PVC mai i te pirau wera, ka whakaiti i te mōrearea o ngā ara iahiko poto.
Ngā Take hei Whakaaroaro i te Wā e Kōwhiria ana ngā Whakapūmau Wera PVC
Ko te whiriwhiri i te whakaū wera PVC tika e whakawhirinaki ana ki ētahi āhuatanga, tae atu ki te momo PVC (pakari, ngāwari rānei), te tikanga tukatuka, te whakamahinga mutunga, ngā whakaritenga ture, me te utu. Hei kaihanga whakaū PVC pono, ka tohutohu a TOPJOY CHEMICAL i ngā kaihoko kia whai whakaaro ki ēnei mea e whai ake nei:
