Hydroxypropyl methylcellulose yakakamurwa kuita mhando mbiri: mhando yemvura inodziya inodziya (normal hot-melt type) uye mhando yemvura inotonhora (cold-water instant type).
Kushandiswa kweHydroxypropyl methylcellulose
1. Gypsum series Muzvigadzirwa zvegypsum series, cellulose ethers dzinonyanya kushandiswa kuchengetedza mvura uye kuwedzera kutsetseka. Pamwe chete dzinopa zororo. Dzinogona kugadzirisa kusava nechokwadi kwekutsemuka kwemadhiramu uye simba rekutanga panguva yekuvaka uye kuwedzera nguva yekushanda.
2. Muputty yezvigadzirwa zvesimende, cellulose ether inonyanya kuita basa rekuchengetedza mvura, kunamira uye kutsvedzerera, kudzivirira kutsemuka uye kupera simba kwemvura kunokonzerwa nekurasikirwa nemvura zvakanyanya, uye pamwe chete zvinowedzera kunamira kweputty uye kuderedza kuitika kwemaitiro ekuvaka, uye zvinoita kuti kuvaka kuve nyore.
3. Pendi yeLatex Muindasitiri yekupeta, maether ecellulose anogona kushandiswa sezvinhu zvinogadzira firimu, zvinosimbisa, zvinogadzirisa uye zvinosimbisa, zvichiita kuti zvive nekudzivirira kukwesha, kushanda kwakafanana kwepeta, kunamira uye kukosha kwePH, uye zvine kusimba kwepamusoro kwakavandudzwa. Inoshandawo zvakanaka pamwe chete nezvinhu zvinonyungudutsa, uye kuchengetedza kwayo mvura yakawanda kunoita kuti ive yakanaka pakukwesha nekuyera.
4. Mushonga wekubatanidza (interface agent) Unonyanya kushandiswa semuchina wekuomesa, unogona kuwedzera simba rekusunga uye kuchekerera, kuvandudza kufukidza kwepazasi, uye kuwedzera kunamatira uye simba rekusunga.
5. Dura rekudzivirira madziro ekunze. Cellulose ether iri muchinyorwa chino inotarisa pakusungana uye kuwedzera simba, zvichiita kuti dura rive nyore kushandisa uye kuvandudza kushanda zvakanaka. Kudzivirira kusamira, kuchengetedza mvura yakawanda kunogona kuwedzera nguva yebasa redura, kuvandudza kuramba kupfupika nekutsemuka, kuvandudza kunaka kwenzvimbo uye kuwedzera simba redu.
6. Zviumbwa zvehuchi. Muzviumbwa zvitsva zvehuchi, zvigadzirwa izvi zvinotsvedzerera, zvinochengeta mvura uye zvine simba.
7. Chisimbiso, suture Kuwedzerwa kwe cellulose ether kunoita kuti ive nekubatana kwakanaka kwemucheto, mwero wekudzikisa zvishoma uye kuramba kupfeka zvakanyanya, uye kudzivirira data riri pasi kubva mukukuvadzwa kwemakanika, zvichidzivirira kukanganiswa kwekunyorova pakuvaka kwese.
8. Kuzvienzanisa Kubatana kwakasimba kwe cellulose ether kunoita kuti ikwanise kuyerera zvakanaka uye kuzvienzanisa, uye mwero wekuchengetedza mvura unoshanda unoigonesa kugadzika nekukurumidza, zvichideredza kutsemuka nekupfupika.
9. Kugadzira dhaka rekupurasita dhaka Kuchengetedza mvura yakawanda kunoita kuti simende ive nemvura yakakwana, kunowedzera simba rekubatanidza, uye panguva imwe chete kunowedzera simba rekudhonza nekuchekerera, izvo zvinovandudza zvikuru mhedzisiro yekuvaka uye kushanda zvakanaka kwebasa.
10. Kunamira mataira Kuchengeta mvura yakawanda hakudi kuti mataira nematombo epasi zvinyorwe kana kunyoroveswa, izvo zvinovandudza simba rekubatanidza, nguva refu yekuvaka matope, kuvaka kwakaenzana uye kwakanaka, kuvaka kuri nyore, uye kudzivirira kufamba zvakanaka.
Nzira yekunyungudutsa
1. Tora huwandu hunodiwa hwemvura inopisa, uiise mumudziyo woipisa kusvika pamusoro pe85°C, wobva wawedzera chigadzirwa ichi zvishoma nezvishoma uchikurunga zvishoma nezvishoma. Cellulose inoyangarara pamusoro pemvura pakutanga, asi inopararira zvishoma nezvishoma kuti iite slurry yakafanana. Tonhodza mushonga nekukurunga.
2. Kana kupisa 1/3 kana 2/3 yemvura inopisa kusvika pa85— kana kupfuura, wedzera cellulose kuti uwane slurry yemvura inopisa, wobva wawedzera huwandu hwemvura inotonhora yasara, ramba uchikurunga, wotonhodza musanganiswa wabuda.
Zvekungwaririra
Kusviba kwakasiyana-siyana (60,000, 75,000, 80,000, 100,000), kwakarongedzwa mumadhiramu emakadhibhodhi akafukidzwa nefirimu repolyethylene, huremu hwese padhiramu: 25kg. Dzivirirai zuva, mvura uye hunyoro panguva yekuchengetera nekutakura.
