Izinamathiseli zibalulekile ezimbonini eziningi, kusukela ekupakisheni nasekwakheni kuya ezimotweni kanye nasezintweni zikagesi. Zisetshenziselwa ukuhlanganisa izinto ndawonye, zinikeze amandla nokuqina kuze kube umkhiqizo wokugcina. Ngokwesiko, izinamathiseli zakhiwe kusetshenziswa izincibilikisi, okuyizinto eziphilayo eziguquguqukayo (ama-VOC) ezingadala izingozi zempilo kanye nezemvelo. Kodwa-ke, njengoba ukukhathazeka kukhula ngomthelela wezincibilikisi, abantu baphendukela ezincibilikisini ezingenazincibilikisi njengendlela ephephile neqhubekayo.
Ngakho-ke, uyini umehluko phakathi kwezinamathelisi ezisekelwe ku-solvent kanye nezinamathelisi ezingena-solvent? Umehluko omkhulu usekwakhekeni nasekusetshenzisweni kwazo. Izinamathelisi ezisekelwe ku-solvent ziqukethe amakhemikhali e-organic aguquguqukayo asebenza njengezithuthi zokusabalalisa izithako zokunamathelisa. Lezi zinamathelisi ziyanyamalala ngesikhathi senqubo yokwelapha, zishiye isibopho esiqinile. Izinamathelisi ezingena-solvent, ngakolunye uhlangothi, zakhiwe ngaphandle kokusebenzisa izinamathelisi futhi esikhundleni salokho zithembele kwezinye izindlela zokwelapha nokubopha.
Enye yezinzuzo eziyinhloko ze-izinamathiseli ezingenayo i-solventizinzuzo zazo zemvelo nezempilo. Izinamathiseli ezisekelwe ku-solvent zikhipha amakhemikhali e-organic ayingozi aguquguqukayo emoyeni, okubangela ukungcola komoya futhi kubeka izingozi empilweni kubasebenzi nakubathengi. Ngokuphambene nalokho, izinamathiseli ezingenazo izincibilikisi zisusa isidingo sezincibilikisi, zinciphise ukukhishwa kwegesi futhi zidale indawo yokusebenza ephephile. Lokhu kuzenza zibe inketho eqhubekayo ezinkampanini ezifuna ukunciphisa ukunyathela kwazo kwemvelo nokulandela imithethonqubo yokukhishwa kwe-VOC.
Ngaphezu kokuba nobungane nemvelo, izinti ezinamathelayo ezingenayo i-solvent zinikeza ukusebenza okuthuthukisiwe kanye nokuguquguquka. Zaziwa ngamandla azo aphezulu kanye nokuqina, zifaneleka ezinhlelweni ezahlukahlukene okuhlanganisa ukunamathela, ukubopha kanye nokuvala. Ngaphezu kwalokho, izinti ezinamathelayo ezingenayo i-solvent zingenziwa ngezifiso ukuze zihlangabezane nezidingo ezithile njengezikhathi zokuphulukiswa okusheshayo, ukumelana nokushisa kanye nokuguquguquka, okwenza zibe yisisombululo esiguquguqukayo sezimboni ezahlukene.
Omunye umehluko obalulekile phakathi kwezinamathelisi ezisekelwe ku-solvent kanye nezingenaso isinyibilikisi inqubo yazo yokusebenzisa. Izinamathelisi ezisekelwe ku-solvent zivame ukudinga ukuphathwa okukhethekile kanye nokuphefumula ngenxa yokukhishwa kwentuthu eguquguqukayo. Ngokuphambene nalokho, izinamathelisi ezingenaso isinyibilikisi zingasetshenziswa ngokuphephile nangendlela ephumelelayo, kunciphisa isidingo sezinhlelo zokuphefumula ezibizayo kanye nemishini yokuzivikela. Lokhu akugcini nje ngokuthuthukisa izimo zokusebenza ezijwayelekile kodwa futhi kwenza inqubo yokukhiqiza ibe lula, okuholela ekongeni izindleko kanye nokwanda kokukhiqiza.
Ngaphezu kwalokho, ukushintshela kuma-glue angenazo izinyibilikisi kuhambisana nesidingo esikhulayo semikhiqizo esimeme futhi enobungani nemvelo. Abathengi baya ngokuya beqaphela umthelela wemikhiqizo abayithengayo emvelweni, okwenza izinkampani zifune ezinye izindlela eziluhlaza. Ngokusebenzisa ama-glue angenazo izinyibilikisi, izinkampani zingathuthukisa idumela lomkhiqizo wazo futhi zidonsele abathengi abanobungani nemvelo abagxile ekusimeni.
Sekukonke, ukushintshela kuma-adhesive angenazo izinyibilikisi kumelela isinyathelo esihle esiya endleleni eqhubekayo nenesibopho yobuchwepheshe bokunamathela. Ngokususa ukusetshenziswa kwama-adhesive, la ma-adhesive ahlinzeka ngendawo yokusebenza ephephile, ukusebenza okuthuthukisiwe kanye nezinzuzo zemvelo. Njengoba imboni iqhubeka nokubeka phambili ukusimama kanye nezidingo zomthetho ziba nzima kakhulu, ama-adhesive angenazo izinyibilikisi kulindeleke ukuthi abe yi-adhesive ekhethwayo yezinhlelo zokusebenza ezahlukahlukene. Ukwamukela lobu buchwepheshe obusha akuzuzisi nje ibhizinisi kuphela, kodwa futhi kusiza ekudaleni iplanethi ehlanzekile nenempilo yezizukulwane ezizayo.
