HPMC isebenzisa kwi Detergent

Ibakala le-Detergent ye-HPMC i-hydroxypropyl methyl cellulose imhlophe okanye kancinane inomgubo omthubi omncinane, kwaye ayinavumba, ayinancasa, ayinabungozi. I-solvent esasaza ngokukhawuleza kumxube wamanzi abandayo kunye ne-organic matter, ifikelele kwisigxina esiphezulu kwimizuzu embalwa kwaye yenza isisombululo se-viscous ebonakalayo. Ulwelo lwamanzi lunomsebenzi ongaphezulu, ukukhanya okuphezulu, ukuzinza okuqinileyo, ukunyibilika emanzini akuchaphazeli i-pH. Inokuqina kunye nefuthe lokuchasa umkhenkce kwishampu kunye nejeli yeshawa, kwaye inokugcinwa kwamanzi kunye nepropathi elungileyo yokwenza ifilimu yeenwele kunye nolusu. Ngokunyuka kwezinto ezisisiseko, i-cellulose (i-anti-freeze thickener) ingasetyenziswa kwi-detergents yokuhlamba impahla, i-shampoos kunye neegels zeshawa ukunciphisa iindleko kunye nokufezekisa iziphumo ezifunwayo.

Iimpawu kunye noncedo lokuvasa ibakala amanzi abandayo enyibilikayo cellulose HPMC:
I-1, ukucaphuka okuphantsi, ukushisa okuphezulu kunye nesondo;
I-2, ukuzinza okubanzi kwe-pH, kunokuqinisekisa ukuzinza kwayo kuluhlu lwe-pH 3-11;
3, ukwandisa ugxininiso kwingqiqo;
4. Ukwandisa kunye nokuzinzisa amaqamza ukuphucula ukuvakalelwa kwesikhumba;
5. Ukuphucula ngokufanelekileyo umbane wenkqubo.
I-6, kulula ukuyisebenzisa, amanzi abandayo kwi-dispersion ekhawulezayo akayi kuxubana

Umda wesicelo somgangatho we-HPMC wokucoca:

I-HPMC enyibilikayo ngoko nangoko isetyenziselwa isicoci sempahla, ishampu, ukuhlamba umzimba, isicoci sobuso, isithambiso, ikhrimu, ijeli, itoner, isilungisi seenwele, iimveliso zokumila, intlama yamazinyo, ukuvasa umlomo, amanzi amaqamza okudlala.

Imibandela efuna ingqalelo
Umgangatho wokucoca ongafanelekanga we-HPMC hydroxypropyl methyl cellulose ubonisa ukungafihli kakuhle, ukutyeba okulambathayo, ukungcungcutheka emva kwexesha elide, ezinye zide zibe nokungunda, ukuze kuthintelwe imvula yeselulosi kwinkqubo yokusetyenziswa, kufuneka ishukunyiswe phambi kokungaguquguquki.
Umahluko phakathi kwesisombululo esicothayo kunye nesisombululo esikhawulezileyo seemveliso zeHPMC
I-Hydroxypropyl methyl cellulose (emva koku kuthiwa yi-HPMC) inokwahlulwa ibe yisisombululo esikhawulezileyo nesicothayo, i-HPMC ekhawulezileyo ibhekisa kusetyenziso lwe-agent enqamlezayo kunyango lomphezulu wayo kwinkqubo yokuvelisa, ukuze i-HPMC isasazwe ngokukhawuleza emanzini abandayo, kodwa ayinyibiliki ngokwenene, ngokuvuselela iyunifomu, i-viscosity kancinane emva koko, iyanyibilika; I-HPMC enyibilikayo kancinane ingabizwa ngokuba ziimveliso ezinyibilikayo ezishushu, kumanzi abandayo, zinokuba semanzini ashushu, zisasazwe ngokukhawuleza emanzini ashushu, ngokushukumisa iyunifomu, ibe sisisombululo sobushushu esithotywe kubushushu obuthile (ubushushu bejeli yemveliso yenkampani yam malunga 60 deG C), i-viscosity iya kubonakala ngokukhawuleza, kude kube yinto ecacileyo ye-viscous colloid.
Izalathiso ze-physicochemical zesisombululo esikhawulezileyo kunye nesisombululo esicothayo se-HPMC ziyafana, kodwa ziyahluka kuluhlu lwesicelo.
isisombululo Slow nyibilikisa HPMC ikakhulu isetyenziswa udaka, putty kunye nodaka ukuxuba owomileyo, iyunifomu ukuxuba owomileyo HPMC yahlulwe ngezinye izinto, yongeza amanzi ngoko nangoko emva viscosity, hayi clumping; Ekwenzeni iglu kunye nokugquma, kunokubonakala kubambene kunye isenzeko, kufuneka kusetyenziswe amanzi ashushu okanye ngesakhono sokuphazamiseka okwaneleyo senza ukunyibilika kwayo.
I-HPMC enyibilikayo ekhawulezayo enyibilikayo kune-HPMC enyibilikayo ecothayo inoluhlu olubanzi lwezicelo, kwiputty engwevu ye-calcium esekwe kunye nodaka olusekelwe kwisamente, kunye neglu, i-coating ingasetyenziswa, kwiimeko zealkaline ezikhawulezayo ezinyibilikayo HPMC ngokukhawuleza ukufikelela viscosity. ulungelelwaniso; Kwi-gypsum based mortar, ngenxa ye-gypsum pH acid, ngoko kukhokelela kwi-soluble HPMC encangathi ecothayo kakhulu, kunye nokwakha i-gypsum setting yokuqala ≥3min, ukusetwa kokugqibela ≤30min, nangona udaka olusekelwe kwi-gypsum longeze inani elithile le-retarder ukulibazisa ixesha layo lokubeka, kodwa ixesha lokusebenza alilunganga njengesamente kunye neemveliso ezisekwe kwigypsum, ke ngoko, ezinye izinto zealkaline kufuneka zongezwe ukuphucula ixesha lokuncamathela. ye-HPMC.
