Hydroxyprupylmethylcellose

Overview: inotaurwa seHPMC, chena kana kuti isina-chena fibrous kana granular poda. Kune akawanda marudzi emasero uye anoshandiswa zvakanyanya, asi isu tinonyanya kuonana nevatengi mune yakaoma poda yekuvaka mashandiro ezvishandirwi. Iyo inowanzozivikanwa mheremalose inoreva hypromomellose.

Production Proction: Iyo Main Chinyorwa cheHPMC: Yakanatswa Cotton, methyl chloride, zvimwe zvinhu zvekushandisa, isope, isope, tolue Awa, Press, Pulverize The Cellerose, uye zera rakakodzera kuma 35 ℃, kuitira kuti avhareji yePolymerization yeiyo alkali fiber iri mukati meiyo inodiwa renji. Isa iyo Alkali Fibles muEthery Kettle, Wedzera profylene oxide uye methyl chloride ichidzoka Wobva wawedzera huwandu hwakakodzera hwe hydrochloric acid uye oxalic acid kumvura inopisa pa 90 ° c kugeza zvinyorwa kuti uwedzere vhoriyamu. Dehydrate necentrifuge. Geza kusvikira zvazvakarerekera, uye kana izvo zvinyoro-nyoro mune izvo zvisingasviki 60%, chiomesa nemhepo inoyerera pa130 ° C kusvika pasi pe5%. Basa: Kuchengetwa kwemvura, kuremerwa, thiskotropic anti-sag, mhepo-yekupinza basa rekushanda, kudzorera kurongeka.

Kudzokorora kwemvura: Kuchengeta kwemvura ndiyo yakakosha pfuma ye cellulose ether! Mukugadzirwa kwePutty gypsum mors uye zvimwe zvinhu, cellulose ether application yakakosha. Kuchengetwa kwemvura kwakakwirira kunogona kuita zvizere coment ash uye calcium gypsum (iyo yakawanda zvizere maitiro, iyo yakakura simba). Pasi pemamiriro ezvinhu akafanana, iyo yepamusoro viscosity ye cellulose ether, iri nani kuchengetwa kwemvura (iyo gidhi pamusoro pe100,000 viscosity yakatetepa); Yakakwira dosage, iri nani kuchengetwa kwemvura, kazhinji chidiki chidiki che cellulose ether chinogona kuvandudza kwazvo kuita kwemutungamiriri. Kuchengeta kwemvura, apo zvirimo zvinosvika kune imwe nhanho, maitiro ekuwedzera anowedzera huwandu huwandu hunova zvishoma; Rwiyo rwekuchengetwa kwemvura yemasero ether inowanzo kuderedza kana tembiricha imbine inowedzera, asi imwe yakakwirira-gel cellulose anayo kuita zvakare pakuita zviri nani pasi pemamiriro ekunze epamoyo. Kuchengeta kwemvura. Iko kuwirirana pakati pemamolekora emvura uye cellulose ether melocular maketeni ekupinda mukati memacorrolose maketani uye nekuchengetwa nemvura yakasimba, nekuvandudza mvura, uye nekuvandudza kuchengetwa kwemvura kwesimbe simbe.

Kukakavara, Thisxotropic uye Anti-Sag: Inopa yakanaka viscosity kune yakanyorova motsi! Inogona kuwedzera zvakanyanya kuderedza pakati pevhu rakanyorova uye pamusoro pejasi, uye kugadzirisa basa rekutya-rinoita. Mhedzisiro inoshora yemasero aungana inowedzerawo kuparadzanisa kuparadzaniswa uye homogeneity yezvishandiso zvitsva zvakasanganiswa, kudzivirira kusagadzikana kwekunyora, kusarongeka uye kubuda ropa uye kubuda ropa. Iko kukonzeresa mhedzisiro ye cellulose anaiters pa coment-based zvigadzirwa zvinobva kuViscosity yeCellulose Ether Solutions. Pasi pemamiriro ezvinhu akafanana, iyo yepamusoro yekuona cellulose ether, iri nani zvisizvo zvezvinyorwa zvakasarudzika, asi kana visikoity yakakura kwazvo, ichakanganisa zvinhu zvacho (zvakadai seyakaomeswa trowel uye batch scriper). vanoshanda). Kuzvimiririra-kuyambuka dhaka uye kuzvidzora kongiri iyo inoda yakakwira fluidity inoda kuderera viscosity ye cellulose ether. Uye zvakare, iyo inoshamisa mhedzisiro ye cellulose ether ichawedzera iyo yemvura inodiwa yezvinhu zvemukati-zvakavakirwa uye wedzera gobvu remuumbi. Yakakwira viscosity cellulose ether mhinduro yemvura ine yakakwira thishixotropy, iyo zvakare hombe hunhu hwe cellulose ether. Mhinduro dzemukati dzinowanzove nePseudoplastic, UNXotropic kuyerera zvivakwa pazasi pemagetsi emagetsi emagetsi, Pseudoplasticasity inowedzera nekuwedzera mamelelar uremu kana kusunganidzwa kwemherekukwereta ether. Matema emhando anoumbwa kana tembiricha yakawedzerwa, uye yakakwira thisxotropic kuyerera kunoitika. Cellulose ana vana neyakanyanya kutarisisa uye yakaderera viscosity inoratidza thiskropy kunyangwe pazasi pegomba tembiricha. Ichi chivakwa chakanakira kwazvo kuvakwa kwekuvaka motsi kuti ugadzirise iyo nhanho uye sag. Izvo zvinofanirwa kucherechedzwa pano iyo yakakwira viscosity yeCellulose ether, iko zviri nani kuchengetwa kwemvura, asi kukwirira kwemvura, kuderera kwekonolose ether, uye kuderera kunoenderana mukushushikana kwayo, iyo ine yakaipa kukanganisa pamubhedha wekusungwa uye kushanda.

Chikonzero: Cellulose ether ane zviri pachena mweya-kupinza zvinokanganisa pane nyowani nzvimbo-yakavakirwa zvinhu. Cellulose ether ane ese maHydrophilic Boka (hydroxyl boka, ether group) uye hydrophobic group (methesel group), iri siractant, ine chiitiko chemagetsi, uye nekudaro ine mhepo-yekupindirana. Iyo mhepo-yekupindira mhedzisiro ye cellulose ichabereka "bhora" mhedzisiro, iyo inogona kuwedzera plasitiki yakasanganiswa, sekusanzwisiswa kwepamhepo panguva yekushanda, iyo inobatsira pakuvira kwemutumbi ; Izvo zvichawedzerawo kubudiswa kwemutumbi. , kuderedza mutengo wekugadzirwa kwerufu; Asi ichawedzera rorosimba kwechinhu chakaomeswa uye kuderedza michina yayo michina yakadai sesimba uye elastic modulus. Semunhu anoona, cellulose ether ane yakanyorova kana kuisirwa pamhepo zvikamu zvemhepo, izvo pamwe nemhepo yekupindirana inowedzera iyo simende-yakavakirwa zvinhu, asi mhedzisiro yaro inoderedza iyo flidaity. Mhedzisiro yekuyerera ndeyekubatanidzwa kwekusanganisa uye kwakasiyana mhedzisiro. Kana zvirimo zve cellulose ether zvakaderera kwazvo, zvinonyanya kuratidzwa sepfungwa kana kuti mvura-inoderedza mari; Kana zvirimo zvakakwira, mhedzisiro yemasero e cellulose genera inowedzera nekukurumidza, uye iyo yemhepo inokanganisa inowanzogutsa, saka kuita kwacho kuchawedzera. Kukonzeresa kana kuwedzera mvura inodiwa.

Kugadzika kudzoka: cellulose ether kunogona kunonoka hydration maitiro eiyo simende. Cellulose eter eter ine mongwe ine dzakasiyana siyana zvinobatsira, uye zvakare kuderedza iyo yekutanga hydration kusunungurwa kweiyo simende uye kunonoka iyo hydration kinetic maitiro eiyo simende. Izvi hazvina kunaka kushandiswa kwemutumbi munzvimbo dzinotonhora. Uku kudzoreredzwa kunokonzerwa neyemushambadzi we cellulose ether mamorekusa pane hydration zvigadzirwa senge csh naCa (OH) 2. Nekuda kwekuwedzera kweiyo visikopo yemhinduro yemhinduro, iyo cellulose ether inoderedza kusundira kwemhinduro mumhinduro, nekudaro kunonoka kuitwa kwehyration. Iyo yepamusoro kusunganidzwa kwemheremelle ether mune mineral gel zvinhu, iyo inonyanya kutaura mhedzisiro yekunonoka kwehyration. Cellulose eriners kwete chete kudzosera kuronga, asi zvakare zvakare kudzosera maitiro ekuomesa kweiyo simende yemutumbi system. Iko kudzoreredzwa kwemasero yemasero ether kunoenderana kwete chete pakusangana kwayo mune yemaminerari gel system, asi zvakare pazvinhu zvemakemikari. Iyo yakakwira iyo degree re methylation yeHemc, iri nani iyo kudzoreredzwa kwemhedzisiro ye cellulose ether. Mari yekudzoserwa yakasimba. Nekudaro, iyo viscosity ye cellulose ether ine zvishoma mhedzisiro pane hydration kinetics ye simenti. Nekuwedzera kwemasero eCellulose ecther yezvinyorwa, iyo nguva yekugara yevhu inowedzera zvakanyanya. Iko kune yakanaka isina kuwirirana pakati peiyo yekutanga nguva yekuisa nguva yedhaka uye zviri mukati meCellulose ether, uye yekupedzisira nguva yekugadzirisa mutsara weCellulose ether. Isu tinogona kudzora nguva yekushandisa yemutumbi nekuchinja zvirimo muCellulose Ether. Muchigadzirwa, inopa basa rekuchengeta kwemvura, kurira, kunonoka kweiyo hydration simba, uye kuvandudza mashandiro ekuvaka. Kuchengetwa kwemvura kwakanaka kunoita kuti cyment (inowedzera zvakanyanya kusungwa kwevhu, uye panguva imwecheteyo inogona kuvandudza simba rekuvaka uye sesimba rekuvaka uye nekubudirira kwebasa. Nguva inogadziriswa. Inovandudza kupuruzira kana kusvina kweguruva, pamwe nesimba remuviri. Muchiitiko chaicho chekushandisa, chinodiwa kuti uone mhando yacho, viscosity, uye huwandu hwemasangano maererano nezvakagadzirwa, tsika dzekuvaka, uye nharaunda.
