I-Cellulose ether yi-polymer engeyiyo i-ionic semi-synthetic, i-soluble yamanzi kunye ne-solvent ezimbini, kumashishini ahlukeneyo abangelwa yindima yahlukile, njengakwizinto zokwakha iikhemikhali, inesiphumo esilandelayo se-compound:
① iarhente yokugcina amanzi, ② i-ejenti yokujiya, ③ ukulinganisa, ④ ukwenza ifilimu, ⑤ isibophelelo
Kwishishini lePVC
yi-emulsifier, isabalalisi;
Kumashishini anceda amayeza
luhlobo lwe-binder kunye nokukhululwa okucothayo kwe-skeleton material, kuba i-ether ye-cellulose ineentlobo ezahlukeneyo zeziphumo ezidibeneyo, ngoko ke yeyona ndawo isetyenziswa kakhulu.Ngezantsi ndigxininisa ekusebenziseni i-cellulose ether kwizinto ezahlukeneyo zokwakha kunye nendima.
Kwipeyinti yelatex
Kumgca wepeyinti ye-latex, ukukhetha i-cellulose ye-hydroxyethyl, ukucaciswa ngokubanzi kwe-viscosity elinganayo yi-3000-50000cps, ihambelana neenkcukacha ze-HBR250, i-dosage yereferensi ngokuqhelekileyo i-1.5 ‰-2 ‰.Indima ephambili ye-hydroxyethyl cellulose kwipeyinti ye-latex kukujiya, ukuthintela i-pigment gelation, igalelo ekusasazweni kwe-pigment, i-latex, ukuzinza, kwaye inokuphucula i-viscosity yamacandelo, igalelo ekusebenzeni komgangatho wokwakha: I-hydroxyethyl cellulose kulula ukuyisebenzisa. , zombini amanzi abandayo kunye namanzi ashushu angachithwa, kwaye akachaphazeli ixabiso le-PH.Ingasetyenziswa ngokukhuselekileyo phakathi kwexabiso le-PI 2 kunye ne-12. Iindlela zokusetyenziswa zezi zilandelayo:
I. Yongeza ngokuthe ngqo kwimveliso
Kule ndlela, ukulibaziseka kwe-hydroxyethyl cellulose kunye nexesha lokuchithwa kwemizuzu engaphezu kwe-30 kufuneka kukhethwe.Inkqubo imi ngolu hlobo lulandelayo: (1) ukuba phezulu kufuneka usike blender isikhongozeli umthamo amanzi acocekileyo (2) amandla angaphakathi abantu baqala ukuxubana ngesantya esiphantsi, iyunifomu hydroxyethyl ngokucotha ngaxeshanye ukujoyina isisombululo (3) qhubeka uvuselela de zonke izinto ezimanzi zegranular (4) ukujoyina ezinye izongezo kunye nezongezo zealkali (5) zixhokonxa de zinyibilike ngokupheleleyo zonke i-hydroxyethyl, zongeza amanye amacandelo efomyula, ukugaya kwimveliso egqityiweyo.
2, ixhotyiswe ngotywala bemama
Le ndlela inokukhetha i-cellulose e-soluble ekhawulezayo, kwaye ine-mildew-proof effect.Inzuzo yale ndlela kukuba nokuguquguquka okukhulu, unokudibanisa ipeyinti ye-emulsioni ngqo kuyo, ukwenza indlela iyafana ①–④ inyathelo iyafana.
3, kunye nepapa yokusetyenziswa
Ekubeni izinyibilikisi eziphilayo zizinyibilikisi ezihlwempuzekileyo (ezingenakunyibilika) kwi-hydroxyethyl, zingasetyenziselwa ukulungisa isidudu.I-solvents ye-organic esetyenziswa kakhulu yi-organic liquids kwi-latex paint formulations, njenge-ethylene glycol, i-propylene glycol kunye ne-film forming agents (ezifana ne-diethylene glycol butyl acetate), i-porridge hydroxyethyl cellulose inokongezwa ngokuthe ngqo kwipeyinti, emva kokongeza, qhubeka uvuselela de unyibilike ngokupheleleyo.
Kwi-scraping wall putty
Okwangoku, i-China iphakathi kwesixeko esikhulu sokumelana namanzi, ukuchasana ne-swab ye-putty yokukhusela indalo kuye kwathathwa ngokubalulekileyo ngabantu, kwiminyaka embalwa edlulileyo, ngenxa yokuba i-putty eyenziwe ngeglue yokwakha ikhupha umonakalo wegesi ye-formaldehyde kwimpilo yabantu, isakhiwo. iglu yenziwe nge-polyvinyl alcohol kunye ne-formaldehyde acetal reaction.Ngoko ke lo mbandela ngokuthe ngcembe upheliswe ngabantu, kwaye ukutshintshwa kwesi sixhobo yi-cellulose ether uchungechunge lweemveliso, oko kukuthi, uphuhliso lwezixhobo zokwakha ukhuseleko lokusingqongileyo, i-cellulose yodwa uhlobo lwezinto ezikhoyo ngoku.
Kwi-putty yokumelana namanzi yahlulwe yaba yiputty eyomileyo kunye ne-putty paste iindidi ezimbini, ezi ntlobo zimbini ze-putty zikhetha ngokubanzi i-methyl cellulose kunye ne-hydroxypropyl methyl iindidi ezimbini, ukucaciswa kwe-viscosity ngokubanzi ku-40,000-75000cps phakathi kweyona nto ifanelekileyo, kwindima ephambili ye-cellulose. kwi-putty kukugcinwa kwamanzi, ukudibanisa, ukuthambisa kunye nezinye iziphumo.
Ngenxa yokuba i-putty formula yomenzi ngamnye ayifani, ezinye ziyi-calcium engwevu, i-calcium ekhanyayo, i-samente emhlophe, ezinye ziyi-gypsum powder, i-calcium engwevu, i-calcium ekhanyayo, njl. azifani, umyinge jikelele wokudibanisa ngu-2 ‰-3‰ okanye kunjalo.
