I-latex emhlophe luhlobo oluthile lokuncamathelisa, yona ngokwayo iyinto yokudibanisa izinto kunye nezinto zibe yinto enye.Yiklasi ebalulekileyo yeemveliso zeekhemikhali ezintle, kwaye izibonelelo zayo zentlalo kunye nezoqoqosho zikhulu kakhulu.
Icandelo elibalulekileyo le-latex emhlophe yi-vinyl acetate, eyona nto ibaluleke kakhulu kwimveliso ye-latex emhlophe.Kufuneka isetyenziswe kwimveliso ye-latex emhlophe nayiphi na inkampani eqhelekileyo, ngoko ke igama layo lokwenyani yi-polyvinyl acetate emulsion.I-Polyvinyl acetate emulsion yaphuma kwi-1929 kunye nokuveliswa kwemveliso yaqala ngo-1939. Ngenxa yokuba i-adhesive-based adhesive, ayingcolisi, ayinakutsha, kwaye inokusebenza okungcono kuneglue yezilwanyana.Emva kowe-1945, ngokuyinxenye yathatha indawo yeglu yezilwanyana.Ngenxa yokuba inkqubo yokuvelisa i-latex emhlophe yinto emhlophe yobisi eyenziwa yi-polymerized kumaqondo aphezulu, abanye abantu bayibiza ngokuba yi-latex emhlophe, i-latex kunye namanye amagama.
Okwangoku, kwimarike enkulu yokuhombisa, ukusetyenziswa kwe-latex emhlophe engangcolisi kunye nokusingqongileyo kuya kuba kubaluleke ngakumbi nangakumbi, kwaye kuya kuthandwa ngakumbi ngabantu.Kodwa phakathi kweempawu ezininzi zelatex ezimhlophe, abathengi kufuneka bahlule njani phakathi kwe-latex emhlophe elungileyo kunye nembi?
Okokuqala, kufuneka sibuze ukuba yintoni umxholo wayo oqinileyo?Eminye imiphanda inomxholo oqinileyo ophawulwe kuyo.Ukuba akunjalo, unokucela isikhokelo sokuthenga ngokuthe ngqo.Ngokuqhelekileyo, i-latex emhlophe yokusetyenziswa kwendlu inomxholo oqinileyo malunga ne-30% -35%.Ukuba yi-20% -25%, inokuncanyathiselwa kwiplanga eqhelekileyo.Ukuphakama komxholo oqinileyo, ukufuma okuncinci kukho kwi-latex emhlophe kwaye yomelele ukunamathela kwayo.
Okwesibini, ukuba ivenkile ekhethekileyo ifanelekile, unokuvula ibhakethi encinci yokuvavanya kwaye uhombe i-latex emhlophe.I-latex elungileyo emhlophe kufuneka ibe nevumba elicacileyo, ingabi muncu okanye amanye amavumba angathandekiyo.I-latex elungileyo emhlophe ayinayo i-formaldehyde, ngoko ke ikhuselekile kwaye ayinayo ityhefu.
Okwesithathu, i-latex emhlophe oyithengayo emva kwayo iya koma ngokukhawuleza ngexesha lokusetyenziswa.Ngokuqhelekileyo, i-latex emhlophe iya koma ngokupheleleyo emva kweeyure ezingama-24 zokucinezela.Ukuba ayomile, kuthetha ukuba umgangatho we-latex omhlophe awulungile, okanye indawo yokwakha inomswakama kakhulu.
Ekugqibeleni, khangela umbala we-latex emhlophe emva kokumisa.I-latex elungileyo emhlophe iyabonakala emva kokomiswa, kwaye okukhona kubonakala kubhetele.Kwaye emva kokumisa i-latex emhlophe, izinto ezimbini ezinamathele akulula ukuzikhupha ngokukhawuleza, kubonisa ukuba amandla ayo okunamathela anamandla kakhulu.
Khetha i-popar khetha umgangatho ophezulu.Ukususela ngo 1992 , 100 ezizimeleyo R & D , ODM kunye nenkonzo OEM .
Ukwenziwa kwepeyinti yodonga lwangaphakathi kunye nodonga lwangaphandle.
