Cellulose ether isiri-ionic semi-synthetic polymer, mvura-inonyungudika uye inonyungudika maviri, mumaindasitiri akasiyana anokonzerwa nebasa akasiyana, senge mumakemikari ekuvaka zvinhu, ine inotevera musanganiswa mhedzisiro:
① mvura inochengeta mumiriri, ② inokora mumiriri, ③ kuenzana, ④ kugadzira firimu, ⑤ binder
MuPVC indasitiri
iri emulsifier, inoparadzira;
Muindasitiri yemishonga inobatsira
imhando yebhainda uye inononoka kuburitsa skeleton material, nokuti cellulose ether ine zvakasiyana-siyana zvinosanganiswa zvinokonzerwa, saka ndiyo inonyanya kushandiswa munda.Pasi apa ndinotarisa kushandiswa kwe cellulose ether mune zvakasiyana-siyana zvekuvaka uye basa.
Mune latex pendi
Mumutsara wependi yelatex, kusarudza hydroxyethyl cellulose, iyo yakajairika yakaenzana viscosity ndeye 3000-50000cps, inoenderana neHBR250 yakatarwa, iyo referensi dosage kazhinji 1.5 ‰ -2 ‰.Basa guru re hydroxyethyl cellulose mu latex pendi ndeyekukora, kudzivirira pigment gelation, kubatsira mukupararira kwe pigment, latex, kugadzikana, uye inogona kuvandudza viscosity yezvikamu, inobatsira mukuyera kuita kwekuvaka: Hydroxyethyl cellulose iri nyore kushandisa. , zvose mvura inotonhora uye inopisa inogona kunyungudutswa, uye haina kukanganiswa nePH kukosha.Inogona kushandiswa zvakachengeteka pakati pePI kukosha 2 uye 12. Nzira dzekushandisa dzinotevera:
I. Wedzera zvakananga mukugadzirwa
Kune iyi nzira, kunonoka hydroxyethyl cellulose ine nguva yekuparara kweanopfuura maminitsi makumi matatu inofanira kusarudzwa.Maitiro acho ndeaya anotevera: (1) kuve nepamusoro kunofanira kucheka blender mudziyo kuwanda mvura yakachena (2) simba remukati revanhu rakatanga kusanganisa-kumhanya-mhanya, yunifomu yehydroxyethyl zvishoma nezvishoma panguva imwe chete kuti vabatane mumhinduro ye (3) ramba uchikurudzira kusvikira zvinhu zvose zvakanyorova zvegranular (4) kuti ubatanidze zvimwe zvinowedzera uye alkaline additives (5) fambisa kusvikira yanyunguduka zvachose hydroxyethyl yose, wedzera zvimwe zvikamu zvemushonga, uchikuya kune chigadzirwa chapera.
2, yakarongedzerwa doro ramai
Iyi nzira inogona kusarudza yekutsanya - soluble cellulose, uye ine mildew - proof effect.Kubatsira kweiyi nzira kuve neyakakura kuchinjika, inogona kujoinha emulsioni pendi yakananga mukati, kugadzira nzira yakafanana ne ①-④ nhanho yakafanana.
3, ne porridge yekushandisa
Sezvo organic solvents ari urombo solvents (insoluble) nokuda hydroxyethyl, anogona kushandiswa kugadzira porridge.Iyo inonyanya kushandiswa organic solvents ndeye organic zvinwiwa mu latex pendi magadzirirwo, senge ethylene glycol, propylene glycol uye mafirimu ekugadzira ma agents (akadai sediethylene glycol butyl acetate), porridge hydroxyethyl cellulose inogona kuwedzerwa zvakananga kupende, mushure mekuwedzera, ramba uchikurunga kusvikira yapera zvachose.
Mune scraping wall putty
Parizvino, China iri mune yakawanda yeguta rekudzivirira kwemvura, kuramba swab yekuchengetedzwa kwezvakatipoteredza putty kwakatorwa zvakanyanya nevanhu, mumakore mashoma apfuura, nekuti iyo putty yakagadzirwa nekuvaka glue inovhenekera formaldehyde gasi kukuvadza kune hutano hwevanhu, chivakwa. glue inogadzirwa ne polyvinyl doro uye formaldehyde acetal reaction.Saka chinhu ichi chinopedzwa zvishoma nezvishoma nevanhu, uye kutsiviwa kwechinhu ichi ndeye cellulose ether yakatevedzana yezvigadzirwa, ndiko kuti, kuvandudzwa kwekuchengetedzwa kwezvakatipoteredza zvekuvakisa, cellulose ndiyo chete mhando yezvinhu parizvino.
Mumvura inodzivirira putty inokamurwa kuita yakaoma poda putty uye putty paste marudzi maviri, aya marudzi maviri eputty anowanzo sarudza methyl cellulose uye hydroxypropyl methyl marudzi maviri, viscosity specification inowanzo mu40,000-75000cps pakati pezvakakodzera, mubasa guru re cellulose. mu putty ndiko kuchengetedza mvura, kusungirirana, lubrication uye zvimwe zvinokonzeresa.
Nekuti iyo putty formula yemugadziri wega wega haina kufanana, mamwe ane grey calcium, light calcium, chena simende, mamwe ari gypsum powder, grey calcium, light calcium, nezvimwewo, saka iyo speciation viscosity uye infiltration yehuwandu hwe cellulose yemafomu maviri aya. hazvina kufanana, huwandu hwekuwedzera ndeye 2 ‰ -3 ‰ kana zvakadaro.
