Iyini i-methyl tin stabilizer?

I-methyl tinama-stabilizers awuhlobo lwenhlanganisela ye-organotin evame ukusetshenziswa njengeziqinisi ukushisa lapho kukhiqizwa i-polyvinyl chloride (PVC) namanye ama-polymers e-vinyl. Lezi zinzisi zisiza ukuvimbela noma ukunciphisa ukuwohloka kokushisa kwe-PVC phakathi nokucubungula nokusebenzisa, ngaleyo ndlela kuthuthukise ukuqina nokusebenza kwento. Nawa amaphuzu abalulekile mayelana nezinzinzi ze-methyl tin:

Isakhiwo Sekhemikhali:I-Methyl tin stabilizers yizinhlanganisela ze-organotin eziqukethe amaqembu e-methyl (-CH3). Izibonelo zifaka i-methyl tin mercaptides kanye ne-methyl tin carboxylates.

I-Stabilizing Mechanism:Lezi zinzisi zisebenza ngokusebenzisana nama-athomu e-chlorine akhishwe ngesikhathi sokuwohloka kokushisa kwe-PVC. Ama-methyl tin stabilizer anciphisa lawa ma-radicals e-chlorine, awavimbe ekuqaliseni okunye ukusabela kokuwohloka.

Izicelo:I-Methyl tin stabilizers isetshenziswa kabanzi ezinhlelweni ezahlukahlukene ze-PVC, kufaka phakathi amapayipi, okokufakwayo, amaphrofayili, izintambo, namafilimu. Zisebenza kahle kakhulu ezimeni zokucubungula izinga lokushisa eliphezulu, njengalezo okuhlangatshezwane nazo ngesikhathi sokukhipha noma sokubumba umjovo.

Izinzuzo:

Ukuzinza Okushisayo Okuphezulu:Ama-Methyl tin stabilizer ahlinzeka ngokuzinza okushisayo okusebenzayo, okuvumela i-PVC ukuthi imelane namazinga okushisa aphakeme ngesikhathi sokucubungula.

Ukugcina Umbala Okuhle:Banikela ekugcineni ukusimama kombala wemikhiqizo ye-PVC ngokunciphisa ukuguga okubangelwa ukuwohloka kokushisa.

Ukumelana Nokushisa Okuhle Kakhulu:I-Methyl tin stabilizers isiza imikhiqizo ye-PVC ukumelana nokuwohloka ngokuhamba kwesikhathi lapho ichayeke ekushiseni nasezimeni zemvelo.

Ukucatshangelwa Kokulawula:Nakuba kuphumelela, ukusetshenziswa kwezinhlanganisela ze-organotin, okuhlanganisa i-methyl tin stabilizers, kuye kwabhekana nokuhlolwa okulawulwayo ngenxa yokukhathazeka kwemvelo nempilo ehambisana nezinhlanganisela zethini. Kwezinye izifunda, imikhawulo yokulawula noma ukuvinjelwa kuye kwabekwa kwezinye iziqinisi ze-organotin.

Ezinye izindlela:Ngenxa yezinguquko zokulawula, imboni ye-PVC ihlole ezinye izinzisi zokushisa ezinomthelela oncishisiwe wemvelo. Iziqinisi ezisekelwe ku-calcium nezinye izindlela ezingezona amathini ziya ngokuya zisetshenziswa ekuphenduleni imithetho eguquguqukayo.

Kubalulekile ukuqaphela ukuthi izidingo zokulawula zingahluka ngokwesifunda, futhi abasebenzisi kufanele bahambisane nemithetho kanye nemihlahlandlela yendawo lapho bekhetha futhi besebenzisa.I-PVC stabilizers. Hlala uthintana nabahlinzeki, imihlahlandlela yemboni, neziphathimandla ezifanele zokulawula ukuze uthole ulwazi lwakamuva mayelana nezinketho zokuzinzisa nokuhambisana.
