Okokuqala, ibakala leglue yokwakha kufuneka lithathele ingqalelo izinto eziluhlaza.Esona sizathu siphambili sokubekwa kweglue yokwakha kukungahambelani phakathi kwe-acrylic emulsion kunye ne-hydroxypropyl methylcellulose (HPMC).Okwesibini, ngenxa yokungonelanga kwexesha lokuxuba;kukwakho ukusebenza kakubi kweglue yokwakha.Kwiglu yokwakha, kufuneka usebenzise i-cellulose ye-hydroxypropyl ekhawulezayo (HPMC), kuba i-HPMC ichithwa emanzini kuphela, ayinyibiliki ngokwenene.Emva kwemizuzu emi-2, i-viscosity yolwelo yanda ngokukhawuleza, ivelisa isisombululo esicacileyo se-viscous colloidal.Iimveliso ze-Hot-melt, xa zifakwe emanzini abandayo, ziyakwazi ukusabalalisa ngokukhawuleza emanzini abilayo kwaye zinyamalale emanzini abilayo.Xa ubushushu behla kwiqondo elithile lobushushu, i-viscosity ibonakala ngokukhawuleza de iveliswe isisombululo se-viscous colloidal esicacileyo.Idosi ekhuthazwa kakhulu ye-hydroxypropyl methylcellulose (HPMC) kwiglue yokwakha yi-2-4KG.
I-Hydroxypropyl methylcellulose (i-HPMC) ineempawu ezizinzileyo zomzimba kwi-adhesives yokwakha, kwaye inefuthe elihle kakhulu lokususa i-mildew kunye nokuvala amanzi, kwaye ayiyi kuchaphazeleka ngotshintsho kwixabiso le-pH.I-viscosity ingasetyenziswa phakathi kwe-100,000 kunye ne-200,000 s.Kwimveliso, iphezulu i-viscosity, ingcono.I-Viscosity ihambelana ngokungafaniyo kunye namandla oxinzelelo lwebhondi.Ukuphakama kwe-viscosity, iyancipha amandla oxinzelelo.Ngokuqhelekileyo, i-viscosity ye-100,000 s ifanelekile.
Xuba i-CMC namanzi kwaye wenze intlama enodaka ukuze isetyenziswe kamva.Xa ufaka i-CMC yokuncamathisela, yongeza umlinganiselo othile wamanzi abandayo kwitanki yokudibanisa ngomatshini oshukumisayo.Xa umatshini wokuvuselela uqaliswa, kancinane kwaye ngokulinganayo ufefe i-carboxymethyl cellulose kwi-batching tank, kwaye uqhubeke ushukumisa, ukuze i-carboxymethyl cellulose kunye namanzi zidibanise ngokupheleleyo, kwaye i-carboxymethyl cellulose inyibilikiswe ngokupheleleyo.Xa kuchithwa i-CMC, kudla ngokuba yimfuneko ukuba kusasazeke ngokulinganayo kwaye kuxutywe ngokuqhubekayo, ukwenzela ukuba ngcono "ukuthintela ukuhlangana kunye nokudibanisa kwe-CMC emva kokuba idibene namanzi, kunye nokunciphisa ingxaki yokuchithwa kwe-CMC" kunye nokunyusa izinga lokuchithwa kwe-CMC. .
Ixesha lokuxuba alifani nexesha lokuba i-CMC ichithe ngokupheleleyo.zi-2 iinkcazo.Ngokuqhelekileyo, ixesha lokuxuba lifutshane kakhulu kunexesha lokuba i-CMC ichithe ngokupheleleyo, kuxhomekeke kwiinkcukacha.Isiseko sokugweba ixesha lokuxuba kukuba xa i-CMC ihlakazekile ngokulinganayo emanzini ngaphandle kwamaqhuma acacileyo, ukuxuba kunokumiswa, ukuze i-CMC kunye namanzi ingene phakathi komnye nomnye phantsi kweemeko zedatha ye-static.Kukho izizathu ezininzi zokumisela ixesha elifunekayo lokuchithwa ngokupheleleyo kweCMC:
(1) I-CMC kunye namanzi zidityanisiwe ngokupheleleyo, kwaye akukho sixhobo sokwahlula esilulwelo oluqinileyo phakathi kwazo;
(2) I-paste edibeneyo ilungelelaniswe kakuhle kwaye iqhelekile, inomgangatho ogudileyo kunye ogudileyo;
(3) I-paste edibeneyo ayinayo umbala kwaye ibonakala ngokucacileyo, kwaye akukho zincinci kwi-paste.Kuthatha iiyure ezili-10 ukuya kwezingama-20 ukusuka kwixesha apho i-CMC ifakwa kwitanki yokudibanisa kwaye ixutywe namanzi ide inyibilike ngokupheleleyo.
