Gusaba intangiriro ya selile Thickener

Irangi ryatinze ni uruvange rwipimishije, kurota no kwandika polymer, kandi ibiyobyabwenge bigomba gukoreshwa muguhindura urujijo rwayo kugirango bibarwe kuri buri cyiciro cyumusaruro, kubika no kubaka. Inyongera nkiyi zitwa abarimbyi, zishobora kongera ubukwe bwibintu no kunoza ibintu byimiterere ya moteri, niko nanone yitwa abantu.

Ibikurikira byerekana gusa ibiranga ibinini bikunze gukoreshwa na selile nibisabwa mumashusho ya latex.
Cellulosic materials that can be applied to coatings include methyl cellulose, hydroxyethyl cellulose, and hydroxypropyl methyl cellulose. Ikintu kinini kiranga selile ni uko ingaruka zijimye zidasanzwe, kandi irashobora gutanga irangi ingaruka zimwe za sasita, kandi zituma irangi rifite umuyoboro runaka, kubuza irangi ryo gutuma. Imvura kandi ihamye mugihe cyo kubika, ariko, abo babyifuza nabo bafite intege nke zo kunganiza gukema, cyane cyane iyo bakoresheje amanota menshi.

Cellulose ni ibintu byintungamubiri kuri mikorobe, ingamba zo kurwanya mildew zigomba gushimangirwa mugihe uyikoresha. Cellulosic thickeners can only thicken the water phase, but have no thickening effect on other components in the water-based paint, nor can they cause significant interaction between the pigment and the emulsion particles in the paint, so they cannot adjust the rheology of the paint , Generally, it can only increase the viscosity of the coating at low and medium shear rates (commonly referred to as KU viscosity).

1. Hydroxyyeryl selile

Ibisobanuro nicyitegererezo cya hydroxyyerthys ibicuruzwa bya selile biterwa ahanini ukurikije urwego rwo gusimbuza no kureba. Usibye itandukaniro muri vinosity, ubwoko bwa hydroxyithyll selile irashobora kugabanywamo ubwoko busanzwe bwo kwigabanyamo ibintu bisanzwe, ubwoko bwihuse bwakazi, ubwoko bwihuse bwakazi binyuze muburyo bwo gukora. Kubijyanye nuburyo bwo gukoresha, HydroxyAylyl selile irashobora kongerwa mubyiciro bitandukanye mubikorwa byo kubyara. Ubwoko bwihuse burashobora kongerwaho muburyo bwifu bwumye, ariko agaciro ka sisitemu mbere yo kongeramo agaciro ka 7, cyane cyane kuko hydroxyyedy yashongeshejwe imbere ya 7, cyane cyane kuko hydroxyyerves yashonga buhoro buhoro, kandi ahanini haba hari igihe gihagije cyo kwinjira mu gace ka 7, cyane cyane kubera ko HydroxyEthyl Agaciro gahoro gahoro gahoro karashonga. Kandi ahanini haba hari igihe gihagije cyamazi Intambwe zijyanye nayo zirashobora kandi gukoreshwa mugutegura kwibanda kuri kole hanyuma ukongereho kuri sisitemu irangi.

2. HydroxyPropyl Methyl Cellulose

Ingaruka ya HydroxyPropyl Methylcellse ni kimwe na hydroxyyethlceellylcellylcellylcellylcellylcellylcellylcellylcellylcellylcellylcellylcellylcellylcellsellslcellylcellylcellylcellylcellylcellylcellylcellylcellselllcellylcellylcellylcellylcellselllcellylcellselcesellylcellsellslcellslcellsellslcesellylcellselllcellsellslcellsellslcellselcesellylcellsellslcellselcesellylcellse, ni ukuvuga kongera ubuswa ku gipimo cy'iminsi mike. HydroxyPropyl Methylcellse irahanganira imitekerereze yuburyo, ariko amazi yacyo ntabwo aribyiza nkibya hydroxyyethyl selile, kandi ifite ibibi bya kalling mugihe ashyushye. Kubusa-hydroxypropyl methylcellse, birashobora kongewe mumazi mugihe ukoreshwa no gutatana Kuri hydroxypropyl methylcellse nta kuvura hejuru, irashobora gutsindwa kandi yuzuye amazi ashyushye hejuru ya 85 °

3. Methyl selile

Methycellse ifite imitungo isa na hydroxypropylmethylcellcellcelllcellsellsllsllsllcellcells, ariko ntabwo ihamye muri viscositity yubushyuhe.

Hydroxyyeryl selile ni yo yakoreshejwe cyane mu kiraro cya nyakwigendera, kandi ikoreshwa mu gishushanyo kinini, giciriritse ndetse no hasi kandi gito kandi cyo hasi yubaka amarangi ya latex. Byakoreshejwe cyane mubyimbye bya latex irangi rya latex, Ifu ya Gray Calcium latex irangi, nibindi bya kabiri ni hydroxypropyl methylcellse, nayo ikoreshwa mumafaranga runaka kubera kuzamura abakora. Methyl selile irakoreshwa mubishushanyo bya latex, ariko ikoreshwa cyane mubukonje bwimbere kandi hanze yurukuta rwinyuma kubera gusesa ako kanya no kugumana amazi meza. Kugaragaza cyane Methyl selile irashobora guha ishyaka hamwe na thixotropy idasanzwe no kugumana amazi, bigatuma ifite ibintu byiza byo gusiba.
