HEC yo gusiga irangi

HEC ni ngufi kuri hydroxyethyl Cellulose. Hydroxyethyl selileHECni umuhondo wera cyangwa wijimye, utaryoshye, udafite uburozi, fibrous cyangwa ifu ikomeye yateguwe na etherification ya alkaline selulose na okiside ya Ethylene (cyangwa chloroethanol). Nibintu bitari ionic soluble selulose ether. Nka surfactant idafite ionic, usibye kubyimba, guhagarikwa, guhuza, kureremba, gukora firime, gutatanya, kubika amazi no kurinda.

Imiti ibiranga:

1, HEC irashobora gushonga mumazi ashyushye cyangwa akonje, ubushyuhe bwinshi cyangwa guteka ntibigwa, kuburyo ifite uburyo bwinshi bwo gukemuka no kwiyegeranya, hamwe na gel idafite ubushyuhe;

2, idafite ionic irashobora kubana hamwe nandi moko menshi yandi mavuta ya elegitoronike ashonga, surfactants, umunyu, ni umubyimba mwiza wa colloidal urimo umubyimba mwinshi wa electrolyte;

3, ubushobozi bwo gufata amazi burenze kabiri methyl selulose, hamwe noguhindura neza,

4. HEC ifite ubushobozi bwo gukwirakwiza nabi ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ariko ubushobozi bukomeye bwo kurinda colloid.

Kubwibyo, hydroxyethyl selulose ikoreshwa cyane mugukoresha peteroli, gutwikira, kubaka, ubuvuzi nibiribwa, imyenda, gukora impapuro na polymer polymerisation reaction nizindi nzego.

Ibintu nyamukuru byaHECirangi

1.Umutungo wuzuye

Hydroxyethyl selulose (HEC) ni umubyimba mwiza wo gutwikira no kwisiga. Mubikorwa bifatika, guhuza kubyimbye kwayo no guhagarikwa, umutekano, gutatanya no gufata amazi bizatanga ibisubizo byiza.

1. pseudoplastique

Pseudoplastique ni umutungo ubwiza bwibisubizo bigabanuka hamwe no kwiyongera kwihuta. HEC irimo irangi rya latex biroroshye kuyikoresha hamwe na brush cyangwa roller kandi irashobora kongera ubworoherane bwubuso, bushobora no kongera imikorere myiza; Hamp irimo shampo zirimo amazi kandi zifatika, zoroshye kandi ziratatana byoroshye.

1. Kurwanya umunyu

HEC ihamye mubisubizo byumunyu mwinshi kandi ntishobora kubora muri ionic leta. Byakoreshejwe muri electroplating, birashobora gutuma isahani yuzuye yuzuye, ikamurika. Ikigaragara cyane ni ugukoresha borate, silikatike na karubone ya latx irangi, iracyafite ubwiza bwiza cyane.

4.Ikintu

Imiterere ya membrane ya HEC irashobora gukoreshwa mubikorwa byinshi. Mubikorwa byo gukora impapuro, bisizwe hamwe na HEC glazing agent, birashobora gukumira amavuta kwinjira, kandi birashobora gukoreshwa mugutegura izindi ngingo zokemura impapuro; HEC yongerera imbaraga za fibre mugihe cyo kuboha bityo bikagabanya ibyangiritse kuri bo. HEC ikora nka firime irinda by'agateganyo mugihe cyo gupima no gusiga irangi kandi irashobora gukaraba kure yigitambara n'amazi mugihe uburinzi bwayo budakenewe.

1. Kubika amazi

HEC ifasha kugumana ubuhehere bwa sisitemu muburyo bwiza. Kuberako umubare muto wa HEC mubisubizo byamazi birashobora kugera ku ngaruka nziza yo gufata amazi, kuburyo sisitemu igabanya ubushake bwamazi mugutegura. Hatabayeho gufata amazi no gufatira hamwe, isima ya sima izagabanya imbaraga zayo kandi ifatanye, kandi ibumba naryo rizagabanya plastike mukibazo runaka.

Uburyo bwo gukoresha hydroxyethyl selulose HECirangi

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

.

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 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, hydroxyethyl selulose 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 ya nyina

Kubera ko hydroxyethyl selulose ari ifu ya granular ivuwe, biroroshye gufata no gushonga mumazi hamwe nuburyo bukurikira.

Menyesha

4.1 Mbere na nyuma yo kongeramo hydroxyethyl selulose, bigomba guhora bikomeza kugeza igisubizo kiboneye kandi gisobanutse neza.

4.2. Shungura hydroxyethyl selulose mumazi yo kuvanga buhoro. Ntukabishyire mu kigega cyo kuvanga ari kinini cyangwa mu buryo butaziguye mu bwinshi cyangwa hydroxyethyl selulose.

4.Ubushyuhe bwamazi 3 nagaciro ka pH byamazi bifitanye isano bigaragara no gusesa hydroxyethyl selulose, bityo rero tugomba kubyitaho byumwihariko.

4.4Ntukongere ibintu by'ibanze bivanze mbere yuko ifu ya hydroxyethyl selulose yinjizwa n'amazi. Kuzamura pH nyuma yo gushiramo bifasha gushonga.

4.5 Mugihe gishoboka, kongeramo hakiri kare ya mildew inhibitor.

4.6 Iyo ukoresheje hydroxyethyl selulose ya viscosity nyinshi, 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 Uko umwuka usigaye mwinshi mu irangi, niko ubwiza bwiyongera.

2 Ingano ya activate n'amazi muri formula irangi birahuye?

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

4. Igipimo cyibindi bibyimbye bisanzwe muburyo bwo gusiga irangi hamwe nikigereranyo cya dosiyeHEChydroxyethyl selulose.)

5 murwego rwo gukora irangi, gahunda yintambwe yo kongeramo umubyimba birakwiye.

6 Kubera ubukana bukabije nubushuhe bukabije mugihe cyo gutatana.

7 Isuri ya mikorobe yo kubyimba.
