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 angene 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 ngexesha iCMC ifakwa kumxube wezithako zetanki namanzi de inyibilike ngokupheleleyo.
