HydroxyTHETHELCELLELELE HEC yekupenda uye kuungana

HydroxyTHETHELLELCELELELEE (HEC) ndeye polymer yakashandiswa zvakanyanya pakuratidzira uye kuunganidza mafomu nekuda kwezvinhu zvaro zvakatsanangurwa uye zvinoshanda. Iyi poldu-inoyevedza mvura polymer inotorwa kubva ku cellulose, iyo yepamhepo polymer inowanikwa mumasango masero emadziro. HEC chiitiko chose chinopa huwandu hwekuti unopa dzakasiyana siyana dzenzvimbo dzekupenda uye kubatanidza mafambiro, kusanganisira kuremedza, kusimbisa uye kusimbisa kuyerera zvivakwa.

1. Nhanganyaya kuHydroxyTHYL Cellulose (Hec)

(1). Chemical chimiro uye zvivakwa zvehwanda:
HydroxytHyl Cellulose ndeye yakagadziridzwa cellulose ether ine hydroxytHyl mapoka akasungirirwa kune iyo cellulose backbone.
Dhigirii rekutsiva

(2) .solubility uye kuwirirana:
HEC inokanganisa zviri nyore mumvura inotonhora uye inotonhora uye inopisa, ichiita kuti zvive nyore kuisa mumvura-yakavakirwa mvura yekubatanidza.
Izvo zvinowirirana nevamwe vakasiyana vamwe polymers, vanowedzera uye solvent zvinowanzoshandiswa mune pendi uye machira endasitiri.

2.Reological Properties yeHEC mumapendi uye majasi

(1). Kukurira uye Rheology Control:
Imwe yemabasa ekutanga ehec mumakonzo ndeyekuita seanotenda, kupa iyo inodiwa viscosity yekunyorera uye yefirimu fomu.
Hec inobatsira ne rheology kudzora, inodzivirira sag uye inovimbisa kubhururuka kwakanaka kana kusimbisa.

(2.). Pseudoplastic maitiro:
HEC inopa pseudoplastic maitiro ekubatanidza maitiro ekubatanidza mafambiro, zvichireva kuti viscosity inoderera pasi pehembe, kuita application uye kuve nyore.
Iyi ficha yakakosha pakuzadzisa kunyange kufukidzwa uye kuderedza roller kana ma brashi mamaki.

(3.) Kuzeya kwemifananidzo uye mafirita:
Hec inobatsira kumisa pigment uye mafirita, kudzivirira kugadzirisa panguva yekuchengetera uye application.
Kuvandudzwa kweruzhinji kupararira kunowedzera kukura kwemavara uye kugadzikana kweiyo yekupedzisira yekubatira.

3. Zvakanakira kuti zvibodzwa zvehwanda

(1). Kuvandudza Kuchengetwa Kwemvura:
HEC inowedzera kuchengetwa kwemvura muCoating Formas, kudzivirira kusati kwatanga kuoma uye nekuwedzera nguva yakavhurika, iyo inokoshesa kuwana yunifomu kupera.

(2.). Firimu kugadzirwa uye kuderedza:
Kuvapo kwehec mumakonzo kunobatsira kuumba firimu rinoenderera uye rinonamatira iro rinosimudzira kuomerera kune dzakasiyana siyana dzeSubastion.
Iyo inovandudza kuvimbika kwefirimu uye kusimba.

(3.). Kuderedza kupaza:
HEC's rheological zvivakwa zvinobatsira kuderedza spatter panguva ye roller kana brashi application, ichiva yakacheneswa, inoshanda zvakanyanya kuunganidza maitiro.

4.Application Prections uye kuumbwa nhungamiro

(1). Yakakwana kusimbisa uye kushandira mwero:
Kushandisa zvinobudirira kwehec mumachira kunoda kunyatsofungisisa nezvekusangana uye kuumbwa kuenderana.
Kazhinji, kutarisisa kubva ku0,1% kusvika ku2% nehuremu, asi huwandu hwakakwana hunotsamira pane chaiyo yekuumbwa.

(2). ph kunzwa:
Hec Performance inogona kukanganiswa nePH yeCoating Fomu. Kuenderana kwehisheni kune mamwe mahaka anofanirwa kutariswa uye iyo pH yakagadziridzwa kana zvichidikanwa.

(3) .Temperature kugadzikana:
HEC yakagadzikana pamusoro pehuremu hwakawedzera tembiricha, asi kuratidzwa kwenguva refu kune yakakura tembiricha inogona kukonzera kurasikirwa kwe viscossity. Maguru anofanirwa kufunga nezvemamiriro ekushandisa ekushandisa.

5. Uye yekuzvidzora pfungwa

(1). Kukanganisa kwezvakatipoteredza:
Hec inotorwa kubva ku cellulose, chinyorwa chinoshamisa, uye biodegradable. Kukanganisa kwayo kwezvakatipoteredza kunowanzo kuve kwakaderera.

(2.). Regulatory kutevedzera:
Vagadziri vanofanirwa kuve nechokwadi chekuti kushandiswa kwehec kunoenderana nemitemo yemuno nemusangano zvine chekuita nekushandiswa kwemakemikari mukupenda uye nemakonzo.

6. Mangwana maitiro uye mauniti

(1). Kufambira mberi kweec tekinoroji:
Kuenderera mberi kwekutsvaga zvinangwa zvekuvandudza mashandiro ehecs kuburikidza nekugadziridzwa, sekusuma mapoka matsva ekuita kana kururamisa mapoka avo ekugovaniswa kwemanyorerwo.

(2). Green cemistry uye zviitiko zvinosiririsa:
Iyo pendi uye yejasi indasitiri iri kuwedzera kutarisa pakutsigira. Vagadziri vari kuongorora dzimwe nyika dzinoshamwaridzana maitiro uye maitiro, kusanganisira bio-based polymers uye eco-hushamwari sol sol.

HydroxytHellulose (HEC) inoita basa rakakosha muPendi uye Coatings Indasitiri, achibatsira kuvandudza rheology rateology, kushanda uye kushanda kwekushandisa. Kuita kwayo kunoshamisa, kuenderana uye hushamwari hwezvakatipoteredza zvinoita kuti ive yakakosha inowedzera kuwana maitiro ekuita anoitwa mune yemvura inokambaira. Sezvo indasitiri iri ichiramba ichishanduka, kuenderera mberi nekutsvaga uye kuwanda muPolymer Science inogona kutyaira kufambira mberi mukushandiswa kweec nedzimwe polymes dzakafanana mumhinduro dzinochema.
