Ukusetshenziswa
Isengezo sokucubungula irabha Uwoyela we-solvent ungasetshenziswa njengesithambisi kanye ne-plasticizer yerabha. Ngesikhathi senqubo yokuxuba irabha, ungangena phakathi kwamaketanga e-molecular erabha, wandise ibanga phakathi kwamaketanga e-molecular erabha, futhi unciphise ubulukhuni kanye ne-modulus yerabha. Isibonelo, ekucubungulweni kwerabha yemvelo, ukwengeza inani elifanele lamafutha e-solvent kungenza irabha ithambe futhi kube lula ezinqubweni zokubumba ezilandelayo njengokukhipha kanye nokulinganisa. Kungathuthukisa futhi ukunamathela kwerabha. Ngesikhathi sokubopha irabha kanye nezinye izinqubo zokucubungula, uwoyela we-solvent unganika ubuso berabha ukunamathela okufanele ukuze kube lula ukubopha phakathi kwezingxenye ezahlukene zerabha. Isibonelo, lapho kukhiqizwa amathayi ezimoto, izingxenye ezahlukene zethayi (njenge-tread, i-sidewall, i-inner liner, njll.) zidinga ukulaminathwa. Uwoyela we-solvent ungasiza lezi zingxenye ukuthi zihlangane kangcono. I-raber adhesive esekelwe ku-solvent Isetshenziselwa ukulungiselela i-raber adhesive esekelwe ku-solvent. Uwoyela we-solvent ungancibilikisa izingxenye zerabha ukuze wakhe i-glue enamathelayo. Le adhesive ingasetshenziswa ukubopha phakathi kwerabha nerabha, kanye naphakathi kwerabha nezinye izinto (njengensimbi, ipulasitiki). Isibonelo, ekukhiqizweni kwezicathulo, inhlaka yerabha esekelwe ku-solvent ingahlanganisa ngokuqinile irabha engaphansi kanye nezinto ezingenhla ukuqinisekisa ikhwalithi nokuphila kwesevisi yezicathulo.
Uwoyela we-solvent uyisithako esibalulekile sezimboni. Njengamanje, kunezinhlobo ezingaba ngu-400 kuya ku-500 zezithako emakethe. Ukusetshenziswa kwawo ikakhulukazi ukufeza imigomo ethile ngezinqubo ezifana nokuncibilika kanye nokuguquguquka. Uwoyela we-solvent unezinhlobonhlobo zokusetshenziswa. Ukusetshenziswa okukhulu kakhulu kuqala uwoyela we-solvent wopende (owaziwa ngokuthi u-paint thinner), kulandelwe uwoyela we-solvent wamafutha adliwayo, uyinki wokunyathelisa, isikhumba, izibulala-zinambuzane, izibulala-zinambuzane, irabha, izimonyo, amakha, imithi, izingxenye ze-elekthronikhi, njll. "Amanzi" asetshenziswa yizitolo zokuhlanza izingubo ukuhlanza izingubo ezisezingeni eliphezulu empeleni uwoyela we-solvent wokuhlanza izingubo.
Uwoyela we-solvent ungenye yezinhlobo ezinhlanu ezinkulu zemikhiqizo kaphethiloli. Uwoyela we-solvent unezindlela eziningi zokusetshenziswa. Osetshenziswa kakhulu uwoyela we-solvent wokumboza (owaziwa kakhulu ngokuthi uwoyela we-solvent wopende), kulandele uwoyela odliwayo, uyinki wokunyathelisa, isikhumba, izibulala-zinambuzane, izibulala-zinambuzane, irabha, izimonyo, amakha, imithi, izingxenye ze-elekthronikhi, kanye namanye uwoyela we-solvent. Kunezinhlobo ezingaba ngu-400-500 zezinyibilikisi ezithengiswa emakethe, lapho uwoyela we-solvent (izinyibilikisi ze-hydrocarbon, izinhlanganisela ze-benzene) uyingxenye yazo. Uwoyela we-solvent uyinhlanganisela eyinkimbinkimbi yama-hydrocarbon futhi uyavutha kakhulu futhi uyaqhuma. Ngakho-ke, kusukela ekukhiqizweni, ekugcinweni nasekuthuthweni kuya ekusetshenzisweni, kubalulekile ukuvimbela ngokuqinile ukwenzeka kwemililo.
Ukupakisha Nokuthumela
