Ezisetshenziswayo zokuhlanganisa ipulasitiki, ukukhetha kwe-PVC (i-polyvinyl chloride) okunamathelayo kuthinta ngokuqondile amandla ebhondi, ukuqina, kanye nezimo ezisebenzayo. Ngenxa yemvelo ephansi ye-polarity namandla aphezulu e-PVC, izinto ezinamathelayo ezijwayelekile ziyazabalaza ukuzuza izibopho eziqinile. Ngakho-ke, izinto zokunamathela kufanele zikhethwe ngokucophelela ngokusekelwe ezidingweni ezithile.
1. Izinhlobo Eziyinhloko Zezinto Ze-PVC Glue
Okwamanje, okunamathelayo kwe-PVC okujwayelekile kuhlukaniswe ngezinhlobo ezintathu eziyinhloko: okuncibilikisiwe-okusekelwe, i-acrylate{{1}okusekelwe, kanye ne-polyurethane elungisiwe{2}}okusekelwe. I-Solvent{{4}i-PVC enamathelayo esekelwe ku-PVC, esekelwe kuzincibilikisi zemvelo ezifana ne-chloroform ne-cyclohexanone, incibilikisa indawo ye-PVC ukuze yakhe ibhondi yokungena e-intermolecular. Afanele ukubopha ngokushesha amapayipi noma amafilimu e-PVC aqinile, kodwa izindaba zemvelo nezokuphepha ezihlobene nokuhwamuka kwe-solvent kufanele zicatshangelwe. Izinamatheliso ezisekelwe ku-Acrylate{7}zelapha ngokusebenzisa ukusabela kwe-polymerization kwama-monomers asebenza kakhulu, anikeza kokubili ukuguquguquka kanye nokumelana nesimo sezulu. Afanele{9}kakuhle{9}okufanela amaphrofayili amelana nomthelela ohlangeneyo{10}}. Izinamathiselo ze-polyurethane eziguquliwe, ezinokumelana kwazo okuhle kakhulu nokunwebeka kwamanzi, zihamba phambili ezindaweni ezinomswakama noma ngaphansi kwemithwalo enamandla.
2. Ukucatshangelwa Okubalulekile Kokukhetha Okubalulekile
Okokuqala, kubalulekile ukunquma uhlobo lwe-PVC oluboshwe. Ku-PVC ethambile, ukufuduka kwe-plasticizer kungaholela ekulimazeni okunamathelayo, ngakho-ke i-plasticizer{1}}ifomula yokumelana iyakhethwa. Okwesibili, izimo zemvelo (ezifana namazinga okushisa aphakeme kanye nokuchayeka kwe-UV) zidinga okunamathelayo ukuthi kube nokumelana okufanelekile kwezinga lokushisa (ngokuvamile Okukhulu noma okulingana nama-degree angu-80) kanye nokumelana nokuphuzi. Mayelana nezinhlelo zokusebenza zokuxhumana nokudla,{5}}izinto ezingezona ezinobuthi ezihlangabezana namazinga e-FDA noma e-LFGB kufanele zikhethwe. Ngaphezu kwalokho, indlela yokufaka isicelo (efana nokuxubha noma ukufutha) nayo inomthelela ekwakhiweni kwe-viscosity yezinto ezibonakalayo; -izinto zokunamathela ezine-viscosity eziphansi zisebenza kangcono ekungeneni izikhala eziyinkimbinkimbi.
3. Izincomo Ezisebenzayo kanye ne-Trend Outlook
Abasebenzisi bayelulekwa ukuthi baqinisekise imiphumela ehlanganisayo ngesampula encane yokuhlola, okugxile kumandla okuqala kanye{0}}nokumelana nokuguga kwesikhathi eside. Ngemithetho eqinile yezemvelo, ukuthuthukiswa kwezinamatheliso ze-PVC ezisekelwe emanzini-ezisekelwe ku-bio{3}zokuba yinsakavukela. Nakuba kunciphisa ukukhishwa kwe-VOC, lezi zindlela kufanele zilinganisele ukusebenza kahle kwebhondi kanye nokusebenza kwezindleko-ezisebenza kahle. Ukukhetha izinto ezifanele akuthuthukisi ikhwalithi yephrojekthi kuphela kodwa futhi kunweba umjikelezo wempilo womkhiqizo, kukwenze kube yisinqumo esibalulekile ezinhlelweni zokuhlanganisa ze-PVC.
