Kuvaka-Giredhi Cellulose eter (cellulose ether) ndezvePolymer Compounds inowanikwa kuburikidza nemakemikari kugadziridzwa maitiro ezvisikwa zvechisikigo. Ivo vanoshandiswa zvakanyanya muzvinhu zvakaita sevhu, zvipfeko, uye zvinonamatira muindasitiri yekuvaka. Cellulose etana inogona kukamurwa kuva marudzi akati wandei maererano nemhando yavo molecular chimiro uye zvivakwa. Mhando dzakajairika dzinosanganisiraMetHyl Cellulose ether (MC),HydroxyTHYL Cellulose Ether (Hec),Hydroxyprupyl methylcellose (HPMC)uye nhemwa dzadzo. Aya ma cellulose eter ane akasiyana emuviri uye makemikari zvivakwa uye akakodzera kune akasiyana ekuvaka zvinhu uye kugadzirisa zvinodiwa.
1. Methyl Cellulose ether (mc)
Methyl Cellulose Ether ndiyo yekutanga yakagadziriswa cellelose ether uye imwe yeiyo inonyanya kushandiswa-giredhi cellulose ma cellulose. Maitiro ayo makuru anosanganisira:
Solubility:MC inogona kuumba iyo yakajeka colodal mhinduro mumvura inotonhora.
Kukakavara:Muchikepe chekuvaka, mc inogona kuwedzera zvakanyanya zvidzitiro zvemhinduro uye kugadzirisa kuwirirana kwemutya.
Kuchengeta mvura:MC ine kuchengetwa kwemvura kwakanaka uye kunogona kudzivirira zvinobudirira mucheche kubva mukuzvidzwa nekukurumidza panguva yekuvaka, nekudaro tichisimbisa pakuvaka uye gare gare simba.
Kuita Kwekuvaka:Zvinogona kuvandudza kuiswa kwehudyu uye kuwedzera nguva yakavhurika, zvichiita kuti ive nyore kushanda panguva yekuvakwa.
2. HydroxytHyl cellulose ether (hec)
HydroxytHyl Cellulose ether is a cellulose ether ne hydroxytethyl mapoka akaunzwa pane iyo cellulose Molecule. Maitiro ayo makuru anosanganisira:
Solubility:Hec inogona kunyungudutsira nekukurumidza mumvura kuti iite fungidziro yeVickuus Viscous.
Kukakavara:Kuenzaniswa neMc, hec ine simba rakakomberedza uye rinowanzoshandiswa mune zvekuvaka zvinhu zvinoda rheology yepamusoro newiscosity.
Kuchengeta mvura:Hec ine kuchengetwa kwakanaka kwemvura uye kunogona kuchengeta iyo mongwe yakanyorova kwenguva yakareba kuti udzivise muduri kubva pakuomesa uye kupaza.
Anti-kumiswa:Hec inogona kuvandudza kugona kwemusikirwo ezvikamu zvakasimba mune slurry kuti udzivise kana kusimuka.
Anti-Freeze:Hec ine yakanaka shanduko kune yakaderera tembiricha uye inogona kushandiswa munzvimbo dzinotonhora.
3. Hydroxypropyl methylcellose (HPMC)
HydroxyPropyl methylcellose ndeye cellulose ether yakawanikwa nekutsiva iyo hydroxyl boka pane cellulose Molecule nehydroxpropropropropropropropropyl boka. Maitiro ayo makuru anosanganisira:
Solubility:HPMC inogona kunyungudika nekukurumidza mumvura kuti ugadzire yakajeka colod coloid ine yakakwira viscosity.
Kuremedza uye kugadzikana:HPMC ine yakasimba inosimbisa mhedzisiro. Paunenge uchiwedzera vhiza yekuvaka, inogona kuchengetedza kugadzikana kweiyo durwe uye kuderedza kupusa kwezvinhu.
High Tembiricha Kudzivisa:Kuenzaniswa neMC uye Hec, HPMC ine kusimba kwakasimba kune hutsinye hwekupisa, saka zvakakodzera kuvakwa mune dzimwe nharaunda huru dzekushisa.
Hydrolyis kuramba:HPMC ine yakanaka hydrolysis kugadzikana uye yakakodzera kushandiswa munzvimbo dzakanyorova.
4. Zvivakwa zvakazara zve cellulose ana
Kushandiswa kwe cellulose ethers mune yekuvaka indasitiri inonyanya kuenderana nezvivakwa zvakasiyana-siyana, kunyanya mune zvigadzirwa zvakadai kunge madhiri, uye majasi, uye anomisheni. Izvi zvinotevera zviitiko zvinoverengeka zvakazara zve cellulose ana vana:
Kukakavara:Cellulose aunganoravira zvakanyanya kuvandudza pakuvaka kwejasi kana madhiri nekuwedzera zvevatenzi emvura, uye uve nehuremu hwakanaka uye ductility.
Kuchengeta mvura:Muchikamu chekero uye zvimwe zvekuvakisa, iyo yekuchengetwa kwemvura yemasero inobatsira kudzivirira mvura kubva mukuzvidzwa nekukurumidza, inovimbisa kuti yakanamatira panguva yekuvaka, uye inowedzera nguva yekuvhiya.
Crack Resistance:Cellulose ether inogona kubatsira zvinobudirira kusimudzira kupaza kwemidziyo uye kuderedza marara anokonzerwa nekuomesa shringer kana masimba ekunze.
Kupindirwa:Iko kushandiswa kweCellulose ether kunogona kuvandudza kuvenenzvera kwezvinhu zvekushandisa uye kuvandudza kushanda kwebasa revashandi.
Anti-Sedimentation:Kunyanya mukuvakwa kwemvura, cellulose ether inogona kuderedza iyo sedimentation yezvikamu zvakasimba uye chengetedza kuwirirana kweshuwa.
5. Minda yekushandisa
Kuvaka-giredhi cellulose ether inonyanya kushandiswa mumhando dzinotevera dzezvivakwa zvekuvaka:
Moturu:Cellulose ether inogona kuvandudza basa rekushanda, kuchengetwa kwemvura, kupaza kuramba uye kunyengedza kwemotokari, uye kuri kushandiswa zvakanyanya mukuremerwa, uye kupuruzira moturu, kugadzira moter, etc.
Paint:Cellulose ether inogona kushandiswa seyakakoshwa uye inopararira iri pendi kuti uvandudze iyo fluidity uye kushushikana kwependi.
Kunamatira:Kuwedzera cellulose ether kune formula yekunamatira inobatsira kuwedzera iyo visikoka yekuzvinamatira uye kugadzirisa maitiro ekuvaka.
Yakaoma-yakavhenganiswa dhaka:Inoshandiswa mune yakaoma-yakasanganiswa dhiri, inopa imwe kurudziro yekuchengetwa uye yekuchengetwa kwemvura kuti ive nyore kuti isasvibiswe panguva yekuvaka.
Kuvaka-Giredhi Cellulose ether inoshandisa tarisiro mune yekuvaka indasitiri nekuda kwekukakavara kwayo, kuchengetwa kwemvura, kupaza kudzikisira uye zvimwe zvinhu. Mhando dzakasiyana dzecellulose etana(senge mc, hec, hpmc) ine maitiro akasiyana uye mashandisiro ekushandisa. Kusarudza iyo chaiyo cellulose ether inogona kuwana yakakodzera kuita uye mhedzisiro muzvivakwa zvekuvaka. Nekuvandudzwa kwehunyanzvi hwekuvaka uye shanduko mukuda, dzakasiyana siyana uye dzekushandisa dzemasekiniki ether dziri kugara dzichikura, uye mamwe marudzi manyorerwe ema cellaulose uye mafambiro avo anogona kuoneka mune ramangwana.
