Ngaba i-hydroxypropyl methyl seluplose yeyokwakha

Inqanaba le-glue yingxaki kubathengi. Okokuqala, inqanaba le-glue le-glue kufuneka lithathele ingqalelo izinto ezingafunekiyo. Isizathu esiphambili sokwakha izingqibelelo ezinamathela kukungahambelani phakathi kwe-Acrylic Emalsion kunye ne-hydroxypropyl methylcelcelceluplose (HPMC). Okwesibini, ngenxa yexesha lokuxuba elinganeleyo; Kukwakhona iimpawu ezimbi zokwakha iglue. Ekwalokweni kweGlue, kubalulekile ukusebenzisa ikofu ye-hydroxypropyl methylcelcelcelce (i-HPMC), kuba i-HPMC ichithwa njengamanzi, ayinyibiliki. Emva kwemizuzu emi-2, i-viscosity ye-ulwelo inyuka kancinci, ivelisa isisombululo se-colloidal esibonakalayo se-colloidal. Ukunyibilikisa izinto ezishushu, kudibana namanzi abandayo, kungasasazeka ngokukhawuleza kumanzi abilayo, kumanzi abilayo anciphile. Xa iqondo lobushushu liye kwiqondo lokushisa elithile, ukubuyiswa kwe-viscosity kwenzeka de kuveliswe isisombululo se-colloidal esibonakalayo. Ukwakha Glue Hlue HLUCOPOPLL Methyl Selelose (HPMC) ngosetyenziso olucetyiswayo lwe-2-4 kg.

I-HydroxyPOpyl Methyl Selelose (HPMC) kwi-Glue ye-Glue kwiPropathi yeNdawo eZinzileyo, i-villy lock ilunge kakhulu, i-viscosity ingena kwimveliso kunye nemveliso engcono. I-Viscofity ihambelana ngokulinganayo amandla okunamathela. Ukuphakama kwe-viscosity, amandla amanqam. I-Viscofity General 100,000 ifanelekile.

Ngoku ishishini lokuhombisa, i-hydroxypropyl methyl yesicelo se-seluplose ilungelelani

Lingathini na eli nani? Thatha:

Ngqondakalana ngoko nangoko i-cmc ngamanzi ukwenza udaka olunodaka olugcinwelweyo. Xa ufaka i-CMC Passi, inani elithile lamanzi abandayo longezwa kwimbiza ye-batch enamatshini oshukumisayo. Xa umatshini oshukumisayo uqalisa, ibhokisi yebhokisi ye-carboxymethyl seluplose icolile kwaye ifakwe ngokulinganayo kwitanki yamathafa, yenza ibhokisi yebhokisi ye-carboxethyl kunye ne-carboxymethyl yeseluplose inyibilikiswe kakuhle. Xa inyibilikisa iKomiti yoLawulo, ihlala iyimfuneko ukusasaza ngokulinganayo kwaye iqhubeke ngokudibeneyo "

Ixesha lokuxuba lahlukile kwixesha le-CMC yokunyibilikisa ngokupheleleyo. Zimbini iinkcazo. Ngokubanzi, ixesha lokuxuba lifutshane kakhulu kunexesha le-CMC ukunyibilikisa ngokupheleleyo, kuxhomekeka kwiinkcukacha. Ukumiselwa kwexesha lokuxuba kusekwe kubuchule bokuphelisa ukuxuba xa i-CMC ichithwa njengamanzi ngaphandle kwamanzi angenayo, ivumela i-CMC kunye namanzi ukuze angenelwe phantsi komgangatho wedatha yedatha. Sombulula ixesha elifunekayo kwi-CMC ukunyibilikisa ngokupheleleyo izizathu ezininzi:

(1) I-CMC kunye namanzi zityhutyha ngokupheleleyo, kwaye akukho zixhobo zomeleleyo-zolwelo phakathi kwenye;

.

. Ukusuka kwi-CMC ye-CMC yeNgxowa-mali ye-CMC kunye nomxube wamanzi ukugqiba ukupheliswa kufuneka ibe yi-10 ~ 20 iiyure.
