Hunhu hukuru hwehydroxyethyl cellulose ndeyekuti inonyungudika mumvura inotonhora nemvura inopisa, uye haina hunhu hwegelling. Ine huwandu hwakasiyana hwekutsiva, kunyungudika uye kupenya. Hydroxyethyl cellulose solution inogona kugadzira firimu rakajeka, uye ine hunhu hwemhando isiri yeionic isingashande nemaion uye inoenderana zvakanaka.
①Kupisa kwakanyanya uye kunyungudika kwemvura: Kana tichienzanisa nemethyl cellulose (MC), iyo inonyungudika mumvura inotonhora chete, hydroxyethyl cellulose inogona kunyungudika mumvura inopisa kana mvura inotonhora. Hunhu hwekunyungudika uye kusimba kwemuviri, uye gel isina kupisa.
②Kuramba munyu: Nekuda kwerudzi rwayo rusiri rweionic, inogona kugara pamwe chete nemamwe mapolymer anonyungudika mumvura, masurfactants nemunyu zvakasiyana-siyana. Saka, kana ichienzaniswa neionic carboxymethyl cellulose (CMC), hydroxyethyl cellulose ine kuramba munyu kuri nani.
③Kuchengeta mvura, kuenzana, kugadzira firimu: kugona kwayo kuchengetedza mvura kwakapetwa kaviri kupfuura methyl cellulose, ine kuyerera kwakanaka uye kugadzira firimu kwakanaka, kuderedza kurasikirwa nemvura, kusawirirana, uye pabonde rekudzivirira colloid.
Kushandisa hydroxyethyl cellulose
Hydroxyethyl cellulose chigadzirwa che ether che cellulose chisinganyunguduke mumvura, chinoshandiswa zvakanyanya mukugadzira machira, petroleum, polymerization, mushonga, kushandiswa kwezuva nezuva, bepa neinki, machira, ceramics, kuvaka, kurima nedzimwe nzvimbo. Ine mabasa ekukora, kubatanidza, emulsifying, kuparadzira uye kugadzikana, uye inogona kuchengetedza mvura, kugadzira firimu uye kupa colloid effect inodzivirira. Inonyungudika nyore nyore mumvura inotonhora nemvura inopisa, uye inogona kupa mhinduro ine viscosity yakasiyana-siyana. Imwe ye ethers dzinokurumidza dze cellulose.
Pendi imwe yelatex
Hydroxyethyl cellulose ndiyo inonyanya kushandiswa mu latex coatings. Pamusoro pekukora latex coatings, inogonawo kusanganisa, kuparadzira, kudzikamisa uye kuchengetedza mvura. Inoratidzwa nekukora kunoshamisa, kukura kwakanaka kwemavara, hunhu hwekugadzira firimu uye kugadzikana kwekuchengetedza. Hydroxyethyl cellulose imhando ye cellulose isiri ionic inogona kushandiswa mu pH yakakura. Inoenderana zvakanaka nezvimwe zvinhu zviri muchikamu (senge pigments, additives, fillers uye salts). Coatings dzakakora ne hydroxyethyl cellulose dzine rheology yakanaka pamhando dzakasiyana dzekucheka uye ipseudoplastic. Nzira dzekuvaka dzakadai sekukwesha, roller coating, uye spraying dzinogona kushandiswa. Kuvaka kwakanaka, hakusi nyore kudonhedza, kudonha nekupwanya, uye kuenzana kwakanaka.
2 Kugadziriswa kwePolymerization
Hydroxyethyl cellulose ine mabasa ekuparadzira, emulsifying, suspend uye stabilizing mu polymerization kana copolymerization components ye synthetic resins, uye inogona kushandiswa se colloid inodzivirira. Inoratidzwa nekukwanisa kwayo kupararira, "firimu" rakatetepa rezvikamu, saizi yezvikamu zvidiki, chimiro chezvikamu zvakafanana, rudzi rwakasununguka, kuyerera kwakanaka, kujeka kwechigadzirwa uye nyore kugadzirisa. Nekuti hydroxyethyl cellulose inogona kunyungudutswa mumvura inotonhora nemvura inopisa, uye haina gelling temperature point, yakakodzera zvakanyanya kune akasiyana polymerization reactions.
Zvinhu zvakakosha pakuongorora mhando ye dispersant ndeyekumanikidzwa kwepamusoro (kana kuti pakati pechiso), simba repakati pechiso uye tembiricha ye gelation yemvura yayo. Izvi zvinhu zve hydroxyethyl cellulose zvakakodzera polymerization kana copolymerization yema synthetic resins.
Hydroxyethyl cellulose inoenderana zvakanaka nedzimwe ethers dze cellulose dzinonyungudika mumvura uye PVA. Sisitimu yecomposite yakagadzirwa nenzira iyi inogona kuwana mhedzisiro yakazara yekudzidza kubva kune simba reumwe neumwe uye kuwedzera kusasimba kweumwe neumwe. Zvigadzirwa zvecomposite resin hazvingori zvemhando yepamusoro chete, asiwo zvinoderedza kurasikirwa kwezvinhu.
3 kuchera mafuta
Mukuchera nekugadzira mafuta, hydroxyethyl cellulose ine viscosity yakanyanya inoshandiswa zvakanyanya se viscosifier yekuzadza mvura uye kupedzisa mvura. Hyxyethyl cellulose ine viscosity yakaderera inoshandiswa senzira yekuderedza kurasikirwa nemvura. Mumadhaka akasiyana-siyana anodiwa pakuchera, kupedzisa, kusimbisa uye kupwanya, hydroxyethyl cellulose inoshandiswa senzira yekuomesa kuti iwane kuyerera kwakanaka uye kugadzikana kwedhaka. Panguva yekuchera, inogona kuvandudza kugona kwekutakura jecha kwedhaka uye kuwedzera hupenyu hwebasa redhiri. Mumadhaka ekuzadza echikamu chakaderera uye kusimbisa mvura, hunhu hwakanaka hwekuderedza kurasikirwa nemvura hwe hydroxyethyl cellulose hunogona kudzivirira mvura yakawanda kupinda mudhaka remafuta kubva mudhaka, uye hunogona kuvandudza kugona kwekugadzira kwedhaka remafuta.
4 Makemikari ezuva nezuva
Hydroxyethylcellulose ipurasitiki inoshanda, inosunga, inosimbisa, inosimbisa uye inonyungudutsa mushampoo, maspray ebvudzi, ma neutralizer, ma conditioner uye zvizoro; mu detergent powders. Inoshandiswa pakupatsanura tsvina. Hydroxyethyl cellulose inonyunguduka nekukurumidza pakupisa kwakanyanya, izvo zvinogona kukurumidzisa kugadzirwa uye kuvandudza kushanda zvakanaka kwekugadzira. Chinhu chiri pachena che detergents dzine hydroxyethyl cellulose ndechekuti dzinogona kuvandudza kutsvedzerera uye mercerization yemachira.
5 magadzirirwo
Hydroxyethyl cellulose inogona kushandiswa muzvigadzirwa zvekuvaka zvakaita sekongiri yakasanganiswa, madhaka matsva, gypsum plaster kana mamwe madhaka, nezvimwewo, kuchengetedza mvura panguva yekuvaka isati yaoma uye yaoma. Pamusoro pekuvandudza kuchengetwa kwemvura kwezvigadzirwa zvekuvaka, hydroxyethyl cellulose inogonawo kuwedzera nguva yekugadzirisa uye yekuvhurika kwestucco kana mastic. Inoderedza ganda, kutsvedza uye kudzika. Izvi zvinogona kuvandudza mashandiro ekuvaka, kuvandudza kushanda zvakanaka kwebasa, kuchengetedza nguva, uye panguva imwe chete kuwedzera huwandu hwekuwedzera kwestucco, nokudaro ichichengetedza zvinhu zvakagadzirwa.
6 kurima
Hydroxyethyl cellulose inoshandiswa mu emulsion yezvipembenene uye mu suspension formulations se thickener ye spray emulsation kana suspensions. Inogona kuderedza kutenderera kwemushonga uye kuita kuti ubatanidzwe zvakasimba pamashizha emuti, nokudaro ichiwedzera simba rekupfapfaidza mashizha. Hydroxyethyl cellulose inogonawo kushandiswa se fil-forming agent mu seed coating uye coating agent; se linker uye fil-forming agent mu recycling yemashizha efodya.
7 Bepa neInki
Hydroxyethyl cellulose inogona kushandiswa semushonga wehukuru papepa nebhodhi uye semushonga wekukora nekurembedza inki dzinobva mumvura. Mukugadzira mapepa, hunhu hwepamusoro hwehydroxyethyl cellulose hunosanganisira kuenderana nemagum akawanda, resins nemunyu usingasanganisike, furo shoma, kushandiswa kweokisijeni shoma uye kugona kugadzira firimu repamusoro rakatsetseka. Firimu iri rine kupenya kwakaderera pamusoro uye kupenya kwakasimba, uye rinogonawo kuderedza mitengo. Pepa rakakura nehydroxyethyl cellulose remaprinti emhando yepamusoro. Mukugadzira inki inobva mumvura, inki inobva mumvura inokora nehydroxyethyl cellulose inooma nekukurumidza, ine ruvara rwakanaka, uye hainamati.
Machira masere
Inogona kushandiswa semuchina wekubatanidza nekuisa saizi mukudhinda machira nekuisa dhayi uye pendi yelatex; chinowedzera saizi kumashure kwekapeti. Mufayibha yegirazi, inoshandiswa semuchina wekugadzira uye wekubatanidza; mudehwe, inogona kushandiswa semuchina wekugadzirisa uye wekubatanidza. Inopa huwandu hwakakura hwemachira aya kana manamati, zvichiita kuti chipfeko chigadzikane uye chikurumidze uye kujeka kwekudhinda kuve kwakanyatsojeka.
Zviumbwa zvesimbi zvipfumbamwe
Chinosunga chakasimba chekugadzira zviumbwa zveceramic.
10 mazino emazino
