Irangi rya HEC

Irangi ryerekana irangi HEC Hydroxyethyl selulose ni ubwoko bwamazi adafite ionic polymer, ifu yera cyangwa yumuhondo, byoroshye gutemba, bidafite impumuro nziza kandi bitaryoshye, birashobora gushonga mumazi akonje kandi ashyushye, kandi umuvuduko wo gushonga wiyongera hamwe nubushyuhe, muri rusange ntibishobora gushonga muri ibishishwa byinshi.Ifite PH nziza itajegajega hamwe nimpinduka nke zijimye murwego rwa ph2-12.HEC ifite imbaraga nyinshi zo kurwanya umunyu nubushobozi bwa hygroscopique, kandi ifite amazi meza ya hydrophilique.Igisubizo cyamazi cyacyo gifite ibikorwa byubuso kandi ibicuruzwa byinshi byijimye bifite pseudoplastique.Irashobora gukorwa muri firime ya anhydrous ibonerana ifite imbaraga ziciriritse, ntabwo yandujwe byoroshye namavuta, itatewe numucyo, iracyafite firime ya HEC yamashanyarazi.Nyuma yo kuvura hejuru, HEC iratatana kandi ntabwo ihurira mumazi, ariko irashonga buhoro.PH irashobora guhinduka kuri 8-10 hanyuma igashonga vuba.

Ibintu nyamukuru

Hydroxyethyl selulose (HEC) ni uko ishobora gushonga mumazi akonje namazi ashyushye, kandi ikaba idafite ibiranga gel.Ifite intera nini yo gusimbuza, kwikemurira no kwiyegeranya.Ifite ubushyuhe bwiza (munsi ya 140 ° C) kandi ntabwo itanga umusaruro mubihe bya acide.imvura.Hydroxyethyl selulose (HEC) igisubizo irashobora gukora firime ibonerana, ifite ibintu bitari ionic bidakorana na ion kandi bihuza neza.

Nka colloid ikingira, Irangi ryerekana irangi HEC irashobora gukoreshwa muri vinyl acetate emulsion polymerisation kugirango iteze imbere sisitemu ya polymerisiyonike mugice kinini cya PH.Mugukora ibicuruzwa byarangiye gukora pigment, kuzuza nibindi byongeweho bitatanye, bihamye kandi bitanga ingaruka zo kubyimba.Irashobora kandi gukoreshwa kuri styrene, acrylic, acrylic nizindi polymers zahagaritswe nka dispersants, zikoreshwa mumarangi ya latex zirashobora kunoza cyane umubyimba, kunoza imikorere iringaniye.

Uburyo bwo gukoresha hydroxyethyl selulose HEC mumaziirangi

1. Ongeraho neza mugihe cyo gusya pigment: ubu buryo nuburyo bworoshye, kandi igihe cyakoreshejwe ni gito.Intambwe zirambuye nizi zikurikira:

.

(2) Tangira kubyutsa umuvuduko muke hanyuma wongereho buhoro buhoro hydroxyethyl selile

(3) Komeza kubyutsa kugeza ibice byose byashizwemo

(4) ongeramo mildew inhibitor, PH igenzura, nibindi

.

2. ifite ibikoresho byababyeyi bategereje: ubu buryo bwabanje gushyirwamo ingufu nyinshi zamazi ya nyina, hanyuma ukongeramo irangi rya latex, ibyiza byubu buryo ni ibintu byoroshye guhinduka, birashobora kongerwaho muburyo bwo gusiga irangi ibicuruzwa byarangiye, ariko bigomba kuba bibitswe neza .Intambwe nuburyo bisa nintambwe (1) - (4) muburyo bwa 1, usibye ko umutekamutwe muremure udakenewe kandi gusa bamwe mubakangurambaga bafite imbaraga zihagije kugirango fibre hydroxyethyl itatanye neza mubisubizo birahagije.Komeza kubyutsa kugeza bishonge burundu mubisubizo byuzuye.Menya ko inzitizi ya mildew igomba kongerwamo inzoga za nyina vuba bishoboka.

3. Igikoma nka fenologiya: Kubera ko ibishishwa kama ari ibishishwa bibi kuri hydroxyethyl selulose, iyi mashanyarazi irashobora kuba ifite poroji.Amashanyarazi akoreshwa cyane nka Ethylene glycol, propylene glycol, hamwe nubushakashatsi bwa firime (nka hexadecanol cyangwa diethylene glycol butyl acetate), amazi ya barafu nayo adashobora gukemuka, bityo amazi ya barafu akoreshwa kenshi namazi kama muri poroji.Gruel - nka hydroxyethyl selile irashobora kwongerwaho irangi.Hydroxyethyl selulose yujujwe muburyo bwa poroji.Nyuma yo kongeramo lacquer, guhita ushonga kandi bigira ingaruka zo kubyimba.Nyuma yo kongeramo, komeza kubyutsa kugeza hydroxyethyl selulose ishonga burundu kandi imwe.Igikoma gisanzwe gikozwe no kuvanga ibice bitandatu byamazi yumubiri cyangwa amazi ya ice hamwe nigice kimwe cya hydroxyethyl selulose.Nyuma yiminota 5-30, Irangi rya Paint HEC hydrolyzes kandi irazamuka bigaragara.Mu ci, ubuhehere bwamazi buri hejuru cyane kuburyo budashobora gukoreshwa kuri poroji.

4 .Ibintu bikeneye kwitabwaho mugihe utanga hydroxyethyl selulose inzoga za nyina:

Pkwitondera

1 Mbere na nyuma yo kongeramo irangi rya HEC, bigomba gukangurwa kugeza igihe igisubizo kiboneye kandi gisobanutse.

2. Shungura hydroxyethyl selile mu kivange gahoro gahoro.Ntukayongere mu kivangavanga ku bwinshi cyangwa mu buryo butaziguye mu bwinshi cyangwa mu bipimo byerekana irangi rya HEC.

Ubushyuhe bwamazi 3 nigiciro cya pH cyamazi bifitanye isano bigaragara no gusesa irangi rya HEC hydroxyethyl selulose, bityo rero tugomba kubyitaho byumwihariko.

Ntukongere ibintu by'ibanze bivanze mbere yuko Paint ya HEC hydroxyethyl selulose ifu yuzuye amazi.Kuzamura pH nyuma yo gushiramo bifasha gushonga.

5 .Mu buryo bushoboka bwose, hiyongeraho hakiri kare ya mildew inhibitor.

6 Iyo ukoresheje ibishishwa byinshi Paint grade HEC, ubunini bwibinyobwa byababyeyi ntibigomba kuba hejuru ya 2,5-3% (kuburemere), naho ubundi inzoga za nyina ziragoye gukora.

Ibintu bigira ingaruka kumyambarire ya latex

1.Umwuka mwinshi usigaye mwirangi, niko hejuru cyane.

2.Ni ingano ya activate n'amazi muri formula yo gusiga irangi?

3 muri synthesis ya latex, ibisigisigi bya catisale ya oxyde yuzuye.

4. Igipimo cyibindi byabyimbye bisanzwe muburyo bwo gusiga irangi hamwe nigipimo cya dosiye hamwe nicyiciro cya Paint HEC.)

5.Mu nzira yo gukora irangi, gahunda yintambwe yo kongeramo umubyimba birakwiye.

6.Kubera imidugararo ikabije nubushuhe bukabije mugihe cyo gutatana.

7.Isuri ya mikorobe yo kubyimba.
