Irangi rya HEC

UrwegoHEC Hydroxyethyl selulose ni ubwoko bwa polymer idafite amazi-elegitoronike, ifu yera cyangwa umuhondo, ifu yoroshye gutemba, impumuro nziza kandi itaryoshye, irashobora gushonga mumazi akonje kandi ashyushye, kandi umuvuduko wo gushonga wiyongera hamwe nubushyuhe, muri rusange ntibishobora gushonga mubinyabuzima byinshi umusemburo. 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 selile(HEC)ni uko ishobora gushonga mumazi akonje namazi ashyushye, kandi 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 bifite aho bihurira.

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 mu buryo butaziguye iyo usya 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, umugenzuzi wa PH, nibindi

.

. . 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 rwose mubisubizo byuzuye. Menya ko inzitizi ya mildew igomba kongerwamo inzoga za nyina vuba bishoboka.

3. Igikoma nka fenologiya: Kubera ko ibishishwa kama ari imiti mibi ya 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 igera kuri 5-30, icyiciro cya PaintHEChydrolyzes kandi izamuka 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 amanotaHEC, bigomba gukangurwa ubudahwema kugeza igisubizo kiboneye kandi gisobanutse.

2. Shungura hydroxyethyl selulose mumazi yo kuvanga buhoro. Ntukabishyire mu kivangavanga ku bwinshi cyangwa mu buryo butaziguye mu bwinshi cyangwa mu cyiciro cya PaintHEC.

Ubushyuhe bwamazi 3 na pH agaciro kamazi bifitanye isano igaragara no gusesa urwego rwa PaintHEChydroxyethyl selulose, rero igomba kwitabwaho byumwihariko.

Ntukongere ibintu by'ibanze bivanze mbere yicyiciro cya PaintHECifu ya hydroxyethyl selulose yuzuye amazi. Kuzamura pH nyuma yo gushiramo bifasha gushonga.

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

6 Iyo ukoresheje ibishishwa byinshiHEC, 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 bibyimbye bisanzwe muburyo bwo gusiga irangi hamwe nigipimo cya dosiye hamwe nicyiciro cya PaintHEC.)

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.
