Kushandiswa uye basa re cellulose ether mune zvakasiyana-siyana zvekuvaka

Cellulose ether imhando yepolymer isiri yeionic semi-synthetic ine mvura inonyunguduka uye inonyunguduka, iyo inokonzera mabasa akasiyana mumaindasitiri akasiyana, semuenzaniso, muzvinhu zvekuvaka zvemakemikari, ine mabasa anotevera akasanganiswa:

① chinhu chinochengetedza mvura ② chinogokora ③ kuenzana ④ kugadzira firimu ⑤ chinosunga

Muindasitiri yePVC, imulsifier, dispersant; muindasitiri yemishonga, isimbi inosunga uye inodzorwa uye inodzorwa nemidziyo yemapfupa, nezvimwewo. Imhaka yekuti cellulose ine mabasa akasiyana-siyana anobatanidza ndiyo inoita kuti ive nekushandiswa kwakawanda. Zvinotevera zvinotarisa pakushandiswa uye basa re cellulose ether muzvinhu zvakasiyana-siyana zvekuvaka.

(1) Muputty yemadziro:

Parizvino, nyika yedu mumaguta mazhinji, putty isingapindi mvura, isingapindi zvakatipoteredza, yave ichikosheswa nevanhu mumakore mashoma ekutanga, nekuda kwekushandiswa kweglue rekuvaka rakagadzirwa neputty rinoburitsa formaldehyde gasi rinokuvadza hutano hwevanhu, guruu rekuvaka rakagadzirwa nepolyvinyl alcohol uye formaldehyde acetal reaction. Saka zvinhu izvi zvinobviswa zvishoma nezvishoma nevanhu, uye zvinotsiva zvinhu izvi ne cellulose ether series products, kureva kuti, kugadzirwa kwezvinhu zvekuvaka zvine hushamwari zvakatipoteredza, cellulose ndiyo chete chinhu chayo.

Muputty isingapindi mvura, putty yakakamurwa kuita upfu hwakaoma putty uye putty paste mhando mbiri dzeputty, idzi mhando mbiri dzeputty kazhinji dzinosarudza modified methyl cellulose uye hydroxypropyl methyl mhando mbiri dze viscosity specifications kazhinji dziri pakati pe30000-60000cps pakati peakanyanya kukodzera, muputty cellulose basa guru nderekuchengetedza mvura, kubatana, lubrication nedzimwe nzvimbo. Nekuti vagadziri vakasiyana-siyana veputty formula haisi yakafanana, dzimwe dziri grey calcium, light calcium, chena simende, nezvimwewo, dzimwe dziri gypsum powder, grey calcium, light calcium, nezvimwewo, saka maformula maviri ekusarudza maspecifications e cellulose viscosity uye kupinda kwayo kwehuwandu hakusi kwakafanana, huwandu hwe general accession ye 2 ‰ -3 ‰ kana zvakadaro. Mukugadzira putty yemadziro, nekuda kwe substrate yemadziro, mvura inotorwa kubva muzvidhinha (13%, kongiri ye3-5%) inodonha kubva mumhepo, saka kana putty ikarasikirwa nemvura nekukurumidza, ichaita kuti pave nekutsemuka kana kubviswa kwehupfu nezvimwe zviitiko, zvichiita kuti putty isashande zvakanaka, nekudaro mushure mekuwedzera cellulose ether ichagadzirisa dambudziko iri. Asi mhando ye filler, kunyanya mhando ye gray calcium, inonyanya kukosha.

Nekuti cellulose ine viscosity yakakura, nokudaro zvinowedzerawo kunamira kweputty, asiwo kudzivirira kuvakwa kwechiitiko chekurembera, uye kukwesha mushure mekunyorova, kuchengetedza basa nezvimwewo. Muupfu hwakaoma putty cellulose ether inofanira kukodzera kuwedzera mapoinzi, kugadzirwa kwayo, kushandiswa kuri nyore, filler uye zvinowedzera zveupfu hwakaoma musanganiswa wakafanana unogona kuva, kuvaka kuri nyorewo, mvura panzvimbo, nehuwandu hwakawanda nehuwandu hwakawanda.

(2) dhaka rekongiri:

Mudhaka rekongiri, rinosvika padanho rekupedzisira, rinofanira kuita kuti simende iite mvura yakakwana chete, kunyanya mukuvaka kwezhizha, kurasikirwa nemvura nekukurumidza, kutora matanho ekuchengetedza sprinkler zvizere, nzira iyi inokanganisa zviwanikwa zvemvura uye kusagadzikana kwekushanda, chinhu chikuru ndechekuti mvura iri pamusoro chete, uye mvura yemukati haisati yakwana, saka mhinduro yedambudziko renzira yekubatanidza mudhaka rekongiri. Cellulose inowanzo sarudza hydroxypropyl methyl kana methyl cellulose, viscosity specifications iri pakati pe20000 - 60000cps, wedzera 2% - 3%. Munharaunda yese, mwero wekuchengetedza mvura unogona kuwedzerwa kusvika kupfuura 85%, kushandiswa kwedhaka rekongiri nenzira yeupfu hwakaoma hwakasanganiswa zvakaenzana mumvura kunogona kuve.

(3) mu stucco plaster, bonding plaster, embedded plaster:

Nekukura kuri kuita indasitiri yekuvaka nekukurumidza, kuda kwevanhu zvinhu zvitsva zvekuvaka kuri kuwedzerawo. Nekuda kwekuwedzera kwekuziva kwevanhu nezvekuchengetedzwa kwezvakatipoteredza uye kufambira mberi kwekushanda zvakanaka kwekuvaka, zvigadzirwa zvegypsum zvesimende zvakagadzirwa nekukurumidza. Parizvino, zvigadzirwa zvegypsum zvakajairika ipurasita yekukwesha, purasita yekubondera, purasita yakamisikidzwa, glue yemataira nezvimwewo. Brush plaster rudzi rwezvinhu zvepurasita zvemhando yepamusoro zvemadziro emukati nebhodhi repamusoro, izvo zvinoita kuti madziro ave akapfava uye akatsetseka, hapana upfu hunodonha uye substrate inosungirirwa zvakasimba pasina kutsemuka nekudonha, uye ine basa rekudzivirira moto; bonding plaster rudzi rutsva rwebhodhi rekuvaka rine light-board, iro rakagadzirwa negypsum sechinhu chepasi uye rinowedzerwa nezvimwe zvinhu, uye rakakodzera kubatanidza marudzi ese emadziro ekuvaka asina organic, ane hunhu hwezvinhu zvisina chepfu, zvisina kunaka, zvinokurumidza kuomesesa uye zvinokurumidza kusungwa. Yakakodzera kubatana pakati pemhando dzakasiyana dzezvinhu zvekuvaka zvisina kugadzirwa, zvine chepfu, zvisinganhuhwi, zvinokurumidza kuoma, zvinosimbisa kubatana nezvimwe zvinhu, uye chinhu chinotsigira pakuvaka mabhodhi ekuvaka nemabhuroko; gypsum caulk imugero wekuzadza pakati pemabhodhi egypsum pamwe nemugero wekugadzirisa madziro nemakomba.

Zvigadzirwa zvegypsum izvi zvine mabasa akasiyana-siyana, pamusoro pegypsum nezvimwe zvinozadza zvine basa guru, nyaya huru ndeyekuwedzera kwe ether ye cellulose zvinotamba basa guru. Sezvo gypsum yakakamurwa kuita gypsum isina mvura uye semi-anhydrous gypsum, gypsum dzakasiyana dzine mhedzisiro yakasiyana pakushanda kwechigadzirwa, saka kukora, kuchengetedza mvura uye kunonoka kwezvinhu zvekuvaka zvegypsum zvinosarudza kunaka kwezvinhu zvekuvaka zvegypsum. Dambudziko rinowanzoitika pazvinhu izvi nderekuvhurika nekutsemuka, simba rekutanga harigone kuwanikwa, kugadzirisa dambudziko iri, kusarudza rudzi rwe cellulose uye retarder composite kushandiswa kwedambudziko, panyaya iyi, sarudzo yakajairika yemethyl kana hydroxypropylmethyl 30,000 - 60,000cps, huwandu hwekuwedzera hwe1.5% - 2%. Pakati, cellulose iyo inonyanya kukoshesa kuchengetedza mvura inodzoreredza mafuta. Zvisinei, mune izvi, kushandiswa kwe ether ye cellulose semudzoreredzi hakusviki, uye kushandiswa kwe citric acid retarder hakuzokanganisa simba rekutanga.

Mwero wekuchengetedza mvura unowanzo kureva mamiriro ezvinhu apo pasina mvura yekunze inonyudzwa, huwandu hwekurasikirwa nemvura kwechisikigo, kana madziro akaoma, kunyudzwa kwemvura pamusoro pevhu uye kudonha kwemvura kwechisikigo kwechinhu nekukurumidza, zvakafanana zvichaitika madhiramu asina chinhu, chiitiko chekutsemuka. Iyi nzira yekushandisa pakushandisa hupfu hwakaoma hwakasanganiswa, kana kugadzirira mhinduro kunogona kureva kugadzirira mhinduro.

(4) Dura rekudzivirira kupisa rinopisa

Dura rekudzivirira kupisa imhando itsva yezvinhu zvekudzivirira madziro mukati, idura rekudzivirira madziro rakagadzirwa nezvinhu zvekudzivirira kupisa, dura uye binder. Cellulose iri mudura iri, ichinyanya kutarisa pakubatanidza, inowedzera simba. Kazhinji sarudza methyl cellulose Kana ichinyanya kusviba (10000cps kana zvakadaro), chiyero chinowanzova pakati pe2‰-3‰, uchishandisa nzira yekusanganisa hupfu hwakaoma.
