Kuyini i-methyl tin stabilizer?

Ithini le-MethylIzithambisi ziwuhlobo lwe-organotin compound evame ukusetshenziswa njengezithambisi zokushisa ekukhiqizweni kwe-polyvinyl chloride (PVC) kanye namanye ama-polymer e-vinyl. Lezi zithambisi zisiza ukuvimbela noma ukunciphisa ukuwohloka kokushisa kwe-PVC ngesikhathi sokucubungula nokusetshenziswa, ngaleyo ndlela zithuthukise ukuqina nokusebenza kwezinto. Nazi amaphuzu abalulekile mayelana nezithambisi ze-methyl tin:

Isakhiwo Samakhemikhali:Iziqinisi ze-Methyl tin ziyizakhi ze-organotin eziqukethe amaqembu e-methyl (-CH3). Izibonelo zifaka phakathi i-methyl tin mercaptides kanye ne-methyl tin carboxylates.

Indlela Yokuzinzisa:Lezi ziqinisi zisebenza ngokusebenzisana nama-athomu e-chlorine akhishwa ngesikhathi sokuwohloka kokushisa kwe-PVC. Iziqinisi ze-methyl tin ziqeda la ma-radical e-chlorine, ziwavimbele ekuqaliseni ukusabela kokuwohloka okuqhubekayo.

Izicelo:Iziqinisi ze-Methyl tin zisetshenziswa kabanzi ezinhlelweni ezahlukene ze-PVC, kufaka phakathi amapayipi, izinto zokufaka, amaphrofayili, izintambo, namafilimu. Zisebenza kahle kakhulu ezimweni zokucubungula ezishisa kakhulu, njengalezo ezitholakala ngesikhathi sokukhipha noma ukubumba umjovo.

Izinzuzo:

Ukuzinza Okuphezulu Kokushisa:Iziqinisi ze-Methyl tin zinikeza ukuzinza okusebenzayo kokushisa, okuvumela i-PVC ukuthi imelane namazinga okushisa aphezulu ngesikhathi sokucubungula.

Ukugcinwa Okuhle Kombala:Zisiza ekugcineni ukuqina kombala wemikhiqizo ye-PVC ngokunciphisa ukushintsha kombala okubangelwa ukuwohloka kokushisa.

Ukumelana Okuhle Kakhulu Nokuguga Kokushisa:Iziqinisi ze-Methyl tin zisiza imikhiqizo ye-PVC ukuthi imelane nokuwohloka ngokuhamba kwesikhathi lapho ivezwa ekushiseni nasezimweni zemvelo.

Izinto Okufanele Uzicabangele Ngokwemithetho:Nakuba kuyasebenza, ukusetshenziswa kwamakhemikhali e-organotin, okuhlanganisa nama-methyl tin stabilizers, kuye kwabhekana nokuhlolwa komthetho ngenxa yezinkinga zemvelo nezempilo ezihlobene namakhemikhali e-tin. Kwezinye izifunda, kuye kwabekwa imikhawulo noma ukuvinjelwa komthetho kwezinye izithambisi ze-organotin.

Ezinye izindlela:Ngenxa yezinguquko zomthetho, imboni ye-PVC ihlole ezinye izindlela zokuqinisa ukushisa ezinomthelela ophansi emvelweni. Izindlela zokuqinisa ezisekelwe ku-calcium kanye nezinye izindlela ezingezona i-tin ziya ngokuya zisetshenziswa ekuphenduleni imithetho eshintshashintshayo.

Kubalulekile ukuqaphela ukuthi izidingo zomthetho zingahluka ngokwesifunda, futhi abasebenzisi kufanele balandele imithetho nezinkombandlela zendawo lapho bekhetha futhi besebenzisaIziqinisi ze-PVC. Hlala uthintana nabaphakeli, iziqondiso zemboni, kanye neziphathimandla zomthetho ezifanele ukuthola ulwazi lwakamuva mayelana nezinketho zokuzinzisa kanye nokuhambisana nazo.
