Ngopende, ngokwesiko okubizwa nge-peint eChina. Upende obizwa ngokuthi upende uhlanganiswe ebusweni bento ukuthi ivikelwe noma ukuhlotshiswa, futhi ungakha ifilimu eqhubekayo enamathiselwe ngokuqinile entweni ezokwenziwa.
Iyini i-hydroxyethyl cellulose?
I-HydroxYethyl Cellulose (HEC), ophuzi noma okhanyayo, okhanyayo, ongenasisekelo, ongewona ubuthi obuqinile, olungiselelwe ukusabela kokuthenjwa kwe-alkaliline cellulose kanye ne-ethylene oxide (noma i-chlorohydrin), ingeyezingane ezincibilikayo ze-cellulose. Njengoba i-HEC inezindawo ezinhle zokuqina, ukumisa, ukusabalalisa, ukubopha, ukubopha amafilimu, ukuvikela umswakama nokunikeza umswakama, ukuhlinzeka ngemithi, ukunikela, umuthi, i-polymer polymerization nezinye izinkambu.
Kwenzekani lapho i-hydroxyethyl cellulose ihlangana nopende osuselwa emanzini?
Njenge-survic engekho, i-hydroxyyethyl cellulose inezinto ezilandelayo ngokungeziwe, ukumisa, ukubopha, ukuntanta, ukusabalalisa, ukusabalalisa, ukugcinwa kwamanzi kanye nokuhlinzeka ngamanzi nokuhlinzeka ngama-colloid avikelayo:
I-HEC incane emanzini ashisayo noma amanzi abandayo, izinga lokushisa eliphakeme noma elibilayo ngaphandle kwezulu, ukuze libe nobunhlobonhlobo se-soubity kanye ne-viscosity, kanye ne-gelation engeyona eyeshisayo;
Umthamo wokugcina amanzi uphakeme kabili njenge-methyl cellulose, futhi inomthethonqubo ongcono wokugeleza;
Uma kuqhathaniswa ne-methyl cellulose ye-methyl ne-hydroxypropyll methyl celtule, amandla asabalalisayo ka-HEC yiyona ebi kakhulu, kepha ikhono elivikelayo le-collroid linamandla kakhulu.
Akukona-ionic futhi kungahle kube nobubanzi obuningi bakwamanye ama-polymers ancibilikayo, ama-surfactants, nosawoti. Kungumkhulu we-colloidal omkhulu omuhle kakhulu wezixazululo eziphakeme ze-electrolyte;
Ungayisebenzisa kanjani i-Hydroxyethyl cellulose? Ungayifaka kanjani?
Faka ngqo ngesikhathi sokukhiqiza - le ndlela ilula futhi ithatha isikhathi esifushane kunazo zonke.
Faka amanzi ahlanzekile kwibhakede elikhulu elihlome nge-shear mixer ephezulu. Qala ukuvusa ngokuqhubekayo ngejubane eliphansi futhi uluhlunge nge-hydroxyethyl cellulose kwisixazululo ngokulinganayo. Qhubeka nokuvusa kuze kube yilapho zonke izinhlayiya zimanzi. Bese ungeza okulondoloziwe kanye nezithasiselo ezahlukahlukene. Njengombala, izinsiza ezihlakazekile, amanzi e-ammonia, njll zivuse kuze kube yilapho yonke i-hydroxyethylllllel pultule
Ifakwe notshwala bamama
Kuwukulungiselela utshwala bomama onokuhlushwa okuphezulu kuqala, bese wengeza kumkhiqizo. Inzuzo yale ndlela ukuthi inokuguquguquka okukhulu futhi kungangezwa ngqo kumkhiqizo oqediwe, kepha kufanele kugcinwe kahle. Izinyathelo zale ndlela ziyefana nezinyathelo eziningi ngendlela 1; Umehluko ukuthi asikho isidingo se-agaritator ephezulu, futhi ezinye izithambisi ezinamandla anele okugcina i-hydroxyethylllurylliose evumelaniswa ngokufanayo kwikhambi lingaqhubeka ngaphandle kokuvimba kuze kube yilapho kuncibilike ngokuphelele ku-viscous nzima. Kodwa-ke, kufanele kuqashelwe ukuthi i-fungicide kumele ingezwe kuphuzo lotshwala maseningi ngokushesha okukhulu.
Njengoba i-hydroxyethyethyl ephethwe ingaphezulu i-puttery noma i-fibrous swolid, i-lihongde ikukhumbuza ukuthi unake amaphuzu alandelayo lapho ulungiselela i-hydroxyethyyl cellulose makeome wotshwala:
(1) Ngaphambi nangemva kokungeza i-hydroxyethyl cellulose, kufanele ivuswe ngokuqhubekayo kuze kube yilapho isixazululo sisobala futhi sicacile.
(2) Kumele ibonakale kancane ethangini lokuxuba, futhi ungafaki inani elikhulu noma faka ngqo i-hydroxyethyl cellulose ethangini lokuxuba.
(3) Izinga lokushisa lamanzi nenani le-PH emanzini linobudlelwano obukhulu nokuchithwa kwe-hydroxyethyl cellulose, ngakho-ke kufanele kukhokhwe.
(4) Ungangezi ezinye izinto ze-alkali ngayinye kwingxube ngaphambi kwe-hydroxyethyl cellulose powder ifakwe emanzini. Ukuphakamisa i-PH ngemuva kokumanzisa kusiza ukuncibilikisa.
(5) ngangokunokwenzeka, engeza i-antifungal ejenti kusengaphambili
(6) Uma usebenzisa i-high-viscoxyyethyl celtule
