3.Hydroxyethyl Cellulose (HEC) Tono:

I roto i te peita wai, ka whai waahi ki te marara me te tiaki i nga ra, te whakarei ake i te pumau o te tauhohenga o te punaha agglomerate, te whakarite kia rite te tohatoha o te poaka me te parai, me te whai hua o te matotoru, te whakapai ake i te wai.

I roto i te keri hinu, ka whakamahia hei whakapumau me te kaihoko matotoru, hei whakahinuhinu mo te keri pai, te whakaoti me te whakakotahi kia pai ai te rere me te pumau.

I roto i te hangahanga, ka taea te whakamahi HEC hei kaikawe whakapakeke me te kaihoko whakakotahi hei whakapai ake i te rere me te kaha mahi, te whakanui ake i te kaha o te reera tuatahi me te karo i te pakaru.

I roto i te parai me te whakakotahi i te raima, tera pea ka piki ake te kaha pupuri wai me te whakakotahitanga.

I roto i nga matū e whakamahia ana i ia ra, penei i te toothpaste, he pai te ahua o te tinana me te matū, he pai te ahua, he wa roa te rokiroki, he maroke me te kapi.

I roto i te mara Paku, ka taea e ia te whakanui ake i te kiato rauemi, te taapiri i te whakahinuhinu me te maeneene.

I tua atu, he whanui te tono i roto i te mangumangu, te tae kakano me te ta, te hanga pepa, te rongoa, te kai, te ahuwhenua etc.

4.Hydroxyethyl Cellulose (HEC) Te whakamahi tikanga :

Tikanga Tuatahi: Whakauru Totika

1. Ringihia te wai parakore ki roto i te peere kua oti te whakakorikori.

2. I te timatanga ka ata whakaohokia, whakamararatia te HEC ki te otinga.

3. Oho kia makuku katoa nga papura HEC.

4. Tuatahi hoatu ki roto i te kaihoko anti-koriri, katahi ka whakauru atu ki nga taapiri penei i te pigment, disperser etc.

5. Whakakorikoritia kia rewa katoa te HEC me nga taapiri (ka kitea te piki haere o te wairewa), katahi ka whakaurua etahi atu kai hei tauhohe.

Tikanga Tuarua: Whakaritea te Waipiro Whaea mo te Whakamahi

Tuatahi te whakarite i te waipiro mama matotoru, katahi ka hoatu ki roto i te hua. Ko te painga o te tikanga he ngawari, ka taea te whakauru tika te waipiro ki roto i te hua. Ko te tikanga me te huarahi ki te whakamahi he rite ki te 1-4 i roto i te tikanga(Ⅰ),be me whakaoho kia rewa katoa ki roto ki te wairewa piri me te matotoru, katahi ka tuku wawe te kai patu koriri ki roto i te waipiro whaea.

Tikanga Tuatoru: Whakaritea nga Rawa-a-Gruel hei Whakamahi

I te mea ko nga whakarewa pararopi he kore-whakarewa mo te HEC, ka taea te whakamahi ki te whakarite i nga mea rite ki te gruel.Ko te mea tino whakamahia ko te ethylene glycol,propylene glycol me te kaihoko hanga kiriata (hexamethylene-glycol, diethyl glycol butyl acetate etc.)Na he hukapapa. te wai, ka taea hoki te whakarite tahi me nga whakarewa pararopi ki nga mea rite ki te gruel.

Ka taea te whakauru i nga mea penei i te kemu ki roto i te hua na te mea kua tino rukuhia te HEC i roto i nga mea rite ki te gruel, kua tetere ake, ka kuhu ki roto i te hua ka memeha tonu, ka whakatairanga i te matotoru, engari me whakaoho kia rewa katoa.

I te nuinga o te wa ka whiwhihia nga mea penei i te gruel ma te whakaranu i te whakarewa pararopi, te wai tio ranei ki te HEC i roto i te wahanga o te 6:1, i muri i te 5-30 meneti HEC hydrolyzes me te tino pupuhi.Kare te tikanga e whakamahia i te raumati na te wera o te rangi.

5.Arahi Tono mo nga Ahumahi Peita

Nga Paanga Matotoru Teitei

Ko te Hydroxyethy Cellulose e whakarato ana i nga peita taherapa ina koa nga peita PVA teitei me te mahi whakakikorua pai.Ina he whakapiri matotoru te peita, karekau ka puta he pupuhi.

Ko te Hydroxyethy Cellulose he nui ake nga paanga o te whakapawera, no reira ka taea te whakaiti i te inenga, te whakapai ake i te utu o te hanga, me te whakarei ake i te aukati horoi o nga peita.

Nga Ahuatanga Rheological Pai

Ko te wairewa wai o Hydroxyethy Cellulose he punaha kore-Newtonian, a ko nga ahuatanga o te otinga ka kiia ko te thixotropy.

I roto i te ahua pumau, i muri i te rewa katoa o te hua, ka taea e te punaha paninga te pupuri i te ahua tino matotoru me te ahua tuwhera.

I roto i te ahua whakaheke, ka taea e te punaha te pupuri i te ahua o te pokey, te hanga i nga hua me te pai o te rere, kaore e pakaru.

I te wa o te paraihe me te roera whakakikorua, he ngawari te horapa o te hua ki runga i te tïpako, he watea mo te hanga, a, i tenei wa, he pai te aukati mokowhiti.

Ka mutu, i muri i te otinga o te paninga o te peita, ka hoki mai ano te potata o te punaha, ka puta tonu te ahua o te peita.

Te Marara me te Wairewa

Ko te Hydroxyethy Cellulose he rongoa katoa na te whakaroa o te whakakorenga, a, ki te taapiri i te paura maroke, ka taea te aukati i te kake me te whakarite kia timata te whakamakuku i muri i te mararatanga tika o te paura HEC.

Ko te Hydroxyethy Cellulose i muri i te maimoatanga tika o te mata ka taea te whakarite i te tere rewa me te pikinga o te hua.

Pūmautanga Rokiroki

He pai te mahi a te Hydroxyethy Cellulose ki te koriri, he nui te wa rokiroki mo nga peita, me te aukati i te noho o nga poaka me nga whakakii.a
