Ibakala leglue yokwakha ngumba okhathaza abathengi.
1. Ibakala lokunamathiswa kolwakhiwo kufuneka lithathele ingqalelo izinto ezingasetyenziswanga. Isizathu esibalulekileyo sokuqulunqwa komgca we-bonding kukungahambelani phakathi kwe-acrylic emulsion kunye ne-hydroxypropyl methylcellulose (HPMC).
2. Ngenxa yokungonelanga kwexesha lokuxuba; i-adhesive yokwakha nayo inengxaki yokutyeba kakubi. Kwizinto zokuncamathelisa zokwakha, kubalulekile ukusebenzisa ikofu ekhawulezileyo i-hydroxypropyl methylcellulose (HPMC) kuba i-HPMC isasazeke nje emanzini kwaye ayinyibiliki ngokwenene. Emva kwemizuzu emi-2, i-viscosity yolwelo iyanda ngokukhawuleza, ivelisa isisombululo se-colloidal esicacileyo. Iimveliso ezincibilikisiweyo zinokukhawuleza zisasazeke emanzini abilayo kwaye zinyamalale emanzini abilayo xa zidibana namanzi abandayo. Xa iqondo lokushisa lihla kwiqondo elithile lobushushu, i-viscosity retardation iyenzeka de iveliswe isisombululo se-viscous colloidal esicacileyo. Kucetyiswa ngamandla ukuba kusetyenziswe i-2-4 kg ye-hydroxypropyl methylcellulose (HPMC) kwi-adhesives yokwakha.
3. Iimpawu ezibonakalayo ze-hydroxypropyl methylcellulose (HPMC) kwi-adhesives yokwakha zizinzile, i-anti-mildew effect ihle kakhulu, kwaye ayiyi konakala ngotshintsho kwixabiso le-pH. I-viscosity ingasetyenziswa phakathi kwe-100,000 kunye ne-200,000 s, kodwa kwimveliso Xa imveliso, iphezulu i-viscosity, ingcono. I-Viscosity ihambelana ngokungafaniyo namandla oxinzelelo lwe-adhesive. Ukuphakama kwe-viscosity, iyancipha amandla oxinzelelo. Ngokuqhelekileyo, i-viscosity yi-100,000s.
Ngoku kwishishini lokuhombisa, ukusetyenziswa kwe-hydroxypropyl methylcellulose kungqongqo ngakumbi.
Indlela yokwenza lo buninzi? Hamba nawe:
Ngoko nangoko xuba i-CMC namanzi ukwenza incamathiso efana nencamathela kwaye ubeke bucala. Xa ufaka intlama ye-CMC, sebenzisa umxube wokongeza umlinganiselo othile wamanzi abandayo kwimbiza yezithako. Xa umxube uqaliswa, kancinane kwaye ngokulinganayo ufefe i-carboxymethylcellulose kwiitanki yesithako, kwaye uqhubeke uvuselela ukudibanisa ngokupheleleyo i-carboxymethylcellulose namanzi kwaye unyibilikise ngokupheleleyo i-carboxymethylcellulose. Xa uchitha ibhodi yebhubhu, kudla ngokuyimfuneko ukuyichitha ngokulinganayo kwaye iqhubeke ivuselela "ukuthintela ukubunjwa kunye nokubunjwa kwebhodi ityhubhu xa idibana namanzi, ukunciphisa ingxaki yokuchithwa kwebhodi yebhubhu" kunye nokuphucula ukunyibilika kwebhodi yebhubhu. . Izinga lokuchithwa kwekomiti yolawulo.
Ixesha lokuxuba lahlukile kwixesha elithathayo ukuba i-CMC ichithe ngokupheleleyo. Ezi ziinkcazelo ezimbini. Ngokubanzi, ixesha lokuxuba lifutshane kakhulu kunexesha lokuchithwa ngokupheleleyo kwe-CMC, kuxhomekeke kwimeko ethile. Ixesha lokuxuba linqunywe ngokusekelwe kwimigangatho yedatha ye-static. Xa i-CMC ihlakazwe ngokulinganayo emanzini ngaphandle kokudibanisa okucacileyo, ukuxuba kuyapheliswa ukuvumela i-CMC kunye namanzi ukuba ingene enye kwenye.
Kukho izizathu ezininzi zexesha elifunekayo lokuchitha ngokupheleleyo i-CMC:
(1) I-CMC kunye namanzi zidityanisiwe ngokupheleleyo, kwaye akukho sixhobo sokwahlula esilulwelo oluqinileyo phakathi kwazo;
(2) Umxube ufana kwaye ugudile, kwaye umphezulu ugudile kwaye ufumile;
(3) Emva kokuxuba, i-paste ayinambala kwaye ibonakala ngokucacileyo, kwaye akukho zincinci kwi-paste. Kuthatha iiyure ezili-10 ukuya kwezingama-20 ukususela kwixesha iCMC ifakwa ngayo kumxube wezithako zetanki namanzi de inyibilike ngokupheleleyo.
