I-HEC yopende

I-HEC imfushane nge-hydroxyethyl cellulose. IHydroxYethyl CelluloseI-HECIngabe okumhlophe noma okuphuzi okuphuzi, okungenamqondo, okunobuthi, okunobuthi noma okunoshukela okulungiselelwe ukusheshiswa kwe-alkaline cellulose ne-ethylene oxide (noma chloroethanol). I-ether ether ye-tholuble engeyona eye-moulle Njengomuntu ophelelwa yi-eonic, ngaphezu kokuqina, ukumiswa, ukubopha, ukuntanta, ukwakha amafilimu, ukusabalalisa, ukugcinwa kwamanzi.

Okuthakiweyo izici:

1, i-HEC ingachithwa emanzini ashisayo noma abandayo, izinga lokushisa eliphakeme noma ukubilisa alinciphisi, ukuze libe nobubanzi be-soubity kanye ne-viscosity, nejeli elingelona elishisayo;

2, i-nonic yaso enganawo i-ionic ingahlangana nebanga lamanye ama-polymers ancibilikisiwe amanzi, ama-surfactants, usawoti, yi-flooidal emkhulu kakhulu equkethe okuhlushwa okuphezulu kwesixazululo se-electrolyte;

3, Umthamo wokugcina amanzi uphakeme kabili kune-methyl cellulose, ngokuguquguquka okuhle kokugeleza,

I-4. I-HEC inekhono elibi kakhulu lokuhlakazeka ngokuqhathaniswa ne-methyl cellulose ebonakalayo ne-hydroxypropylyl methyl celtule, kepha ikhono elinamandla lokuvikelwa kwe-colloid.

Ngakho-ke, i-Hydroxyyethyl cellulose isetshenziswa kabanzi ekuxhashazweni kwe-petroleum, ukuhlanganisa, ukwakhiwa, umuthi nokudla, izindwangu, ukwenza amaphepha kanye ne-polymer polymerization reaction kanye nezinye izinkambu.

Izakhiwo eziphambili zeI-HECngopende we-latex

1.Impahla ejikelezayo

IHydroxYethyl Cellulose (HEC) yinqwaba ekahle yokuqamba kanye nezimonyo. Ngohlelo lokusebenza olusebenzayo, inhlanganisela yokuqina kwayo ngokumiswa, ukuphepha, ukusabalalisa kanye nokugcinwa kwamanzi kuzokhiqiza imiphumela efanelekile.

1. pseudoplastic

I-Pseudoplaltity yindawo yokubona i-viscosity yesixazululo incipha ngokwanda kwesivinini sokujikeleza. I-HEC equkethe upende we-latex kulula ukuyisebenzisa ngebhulashi noma i-roller futhi ingakhuphula ubushelelezi bobuso, okungakhulisa ukusebenza kahle komsebenzi; Ama-shampoos aqukethe ama-swampwoos anamanzi futhi anamathele, ahlanjululwe kalula futhi ahlakazeka kalula.

1. Ukumelana nosawoti

I-HEC iqinile ezixazululweni ze-saline ezigxile kakhulu futhi ayiboli izifundazwe ze-ionic. Isetshenziswa ku-electroplating, ingenza indawo yokuqoqa iphelele, igqamile ngokwengeziwe. Okuphawuleka kakhulu ukusetshenziswa kwepende, upende we-silialand no-carbonate, kusenokubonakala okuhle kakhulu.

4.Ulwelwesi

Izakhiwo zokwakheka kwe-membrane ze-HEC zingasetshenziswa ezimbonini eziningi. Emisebenzini epakerking, ehlanganiswe ne-ejenti ye-HEC Glazing, kungavimbela ukungena kwamafutha, futhi kungasetshenziswa ukulungiselela ezinye izici zesisombululo sobunzi; U-HEC wenyusa ukuqina kwemicu ngesikhathi senqubo yokuluka futhi ngaleyo ndlela kunciphise ukulimala kwemishini. I-HEC isebenza njengefilimu yesikhashana yokuvikela ngesikhathi sokudaya nokudaya kwendwangu futhi ingagezwa kude nendwangu enamanzi lapho ukuvikelwa kwayo kungadingeki.

1. Ukugcinwa kwamanzi

I-HEC isiza ukugcina umswakama wohlelo usesimweni esifanele. Ngoba inani elincane le-HEC esikhangisweni samanzi lingafinyelela umphumela ongcono wokugcina amanzi, ukuze uhlelo lunciphise isidingo samanzi lapho kulungiswa. Ngaphandle kokugcinwa kwamanzi kanye nokunamathela, udaka kasimende luzonciphisa amandla nokunamathela kwalo, futhi ubumba luphinde lunciphise ububanzi ngaphansi kwengcindezi ethile.

Indlela yesicelo ye-Hydroxyethyl cellulose I-HECku-latex upende

1. Faka ngqo lapho ugaya u-pigment: Le ndlela ilula kakhulu, futhi isikhathi esisetshenzisiwe sifushane. Izinyathelo ezinemininingwane zimi ngalendlela elandelayo:

.

(2) Qala ukushukumisa ngejubane eliphansi futhi kancane kancane engeza i-hydroxyethyl cellulose

(3) Qhubeka nokuvusa kuze kube yilapho zonke izinhlayiya zimanzi

(4) Ngeza i-hlobo invibitor, umlawuli we-PH, njll

.

2 Ifakwe ngo-mama ketshezi olindile: Le ndlela ifakwe okokuqala ngoketshezi lukamama ophakeme, bese ufaka i-latex Paint, inzuzo yale ndlela iguquguqukayo, ingangezwa ngqo kupende imikhiqizo eqediwe, kepha kufanele ibe yisitoreji esifanelekile. Izinyathelo nezindlela zifana nezinyathelo (1) - (4) in Methodway 1, ngaphandle kwalapho umgadli wokusika ophezulu awudingeki futhi kuphela onamandla onamandla ane-hydroxyethyl ukuze ahlakazeke kahle kwikhambi kwanele. Qhubeka uvuse kuze kube yilapho kuncibilika ngokuphelele kwikhambi eliminyene. Qaphela ukuthi invibitor ye-hlobo kufanele ingezwe kuphuzo lotshwala ngokushesha ngokushesha okukhulu.

3 I-solvents esetshenziswa kakhulu efana ne-ethylene glycol, i-plylene glycol, kanye ne-hexadecanol (njenge-hexadecanol noma i-diethylene glycol buyl acetate) futhi amanzi eqhwa avame ukusetshenziswa ngoketshezi lwe-organic ephalilini.

I-Gruel - njenge-Hydroxyethyl cellulose ingangezwa ngqo kupende. I-Hydroxyyethyl celtulose igcwele nge-porridge yafomu. Ngemuva kokungeza i-lacquer, chaza ngokushesha futhi ube nomphumela wokuqina. Ngemuva kokungeza, qhubeka ukuvusa kuze kube yilapho i-hydroxyethyl cellulose ichithwe ngokuphelele futhi iyunifomu. Iphalishi elijwayelekile lenziwa ngokuxuba izingxenye eziyisithupha ze-organic solvent noma amanzi eqhwa ngengxenye eyodwa ye-hydroxyethyl cellulose. Ngemuva kwemizuzu engaba ngu-5-30, i-hydroxyethyl cellulose hydrolyzes futhi iyavela ngokusobala. Ehlobo, umswakama wamanzi uphakeme kakhulu ukuthi uzosetshenziselwa iphalishi.

4.Izindaba ezidinga ukunakwa lapho zihlomisa i-hydroxyethyl cellulose makeoy lophuzo

Njengoba i-hydroxyethyl cellulose iyimpuphu ye-granular elashwa, kulula ukuyiphatha futhi ichithe emanzini ngezindlela ezilandelayo zokuphepha.

Isaziso

4.1 Ngaphambi nangemva kokungeza i-hydroxyethyl cellulose, kufanele ivuswe ngokuqhubekayo kuze kube yilapho isixazululo sisobala futhi sicacile.

4.2 Musa ukungeza ethangini lokuxuba ngamanani amakhulu noma ngokuqondile ku-hydroxyethyethyylylyls ardroxyethyyl.

4.Amazinga ama-3 wamanzi nenani lamanzi anobudlelwano obusobala ekuchitheni kwe-hydroxyethyl celtulose, ngakho-ke ukunakwa okukhethekile kufanele kukhokhwe kuwo.

4.4Ungangezi ezinye izinto eziyisisekelo engxube ngaphambi kwe-hydroxyethyl cellulose powder ifakwe emanzini. Ukukhulisa i-PH ngemuva kokuthambisa kusiza ukuncibilikisa.

4.5 Ngokwengeziwe, ukungezwa ekuqaleni kwe-hlobo invibitor.

4.6 Lapho usebenzisa i-viscosisity ephezulu ye-ydroxyyethyl, ukugcwala kotshwala bamama akufanele kube ngaphezulu kuka-2,5-3% (ngesisindo), uma kungenjalo kunzima ukusebenza ngotshwala.

Izici ezithinta ukubonakala kopende we-latex

1 Ama-bubble asalayo anensalela ngaphezulu ngopende, akhuphuka kakhulu.

2 Ngabe inani le-activator namanzi ngendlela yokupenda elingashintshiwe?

3 ekusekeleni kwe-latex, okusalayo kwe-catalyst oxide axide yenani.

4. Umthamo wabanye abakhulu bemvelo kwifomula yokupenda kanye nesilinganiso somthamo ngeI-HECIHydroxYethyl Cellulose.)

5 Ngenqubo yokwenza upende, ukuhleleka kwezinyathelo ukwengeza ubukhulu kufanelekile.

6 Ngenxa yokuphazamiseka ngokweqile kanye nomswakama owedlulele ngesikhathi sokuhlakazeka.

7 Ukuguguleka kwe-microbial of mkhulu.
