Imikoreshereze n'uruhare rwa eteri ya selulose mu bikoresho bitandukanye by'ubwubatsi

Cellulose ether ni ubwoko bwa polymer idafite ionic semi-synthetic ifite amazi ashonga kandi ishonga, ikora imirimo itandukanye mu nganda zitandukanye, urugero, mu bikoresho by'ubwubatsi bya shimi, ifite imirimo ikurikira:

① ikintu gifata amazi ② ikintu gikomeza ubushyuhe ③ kugabanya ④ gukora firime ⑤ ikintu gifata amazi

Mu nganda za PVC, ni emulsifier, dispersant; mu nganda zikora imiti, ni ibikoresho bifunga kandi bigasohora buhoro buhoro kandi bigagenzurwa, nibindi. Kubera ko cellulose ifite imirimo itandukanye ivanze, ni yo ituma igira uruhare runini mu mikoreshereze n'uruhare rwa cellulose ether mu bikoresho bitandukanye by'ubwubatsi. Ibi bikurikira byibanda ku mikoreshereze n'uruhare rwa cellulose ether mu bikoresho bitandukanye by'ubwubatsi.

(1) Mu gipfunyika cyo ku rukuta:

Muri iki gihe, igihugu cyacu mu mijyi myinshi, putty irinda amazi, idahumanya ibidukikije, yahabwaga agaciro n'abantu, mu myaka mike ya mbere, bitewe n'ikoreshwa rya kole y'ubwubatsi ikozwe muri putty irabagirana imyuka ya formaldehyde yangiza ubuzima bw'abantu, kole y'ubwubatsi ikorwa muri alukolo ya polyvinyl na formaldehyde asetal reaction. Bityo, ibi bikoresho bikurwaho buhoro buhoro n'abantu, kandi ibi bikoresho bisimbura ibi bikoresho ni cellulose ether series products, ni ukuvuga iterambere ry'ibikoresho by'ubwubatsi birengera ibidukikije, cellulose ni yo yonyine ikoreshwa.

Muri putty idakira amazi igabanyijemo ifu yumye putty na putty paste ubwoko bubiri bwa putty, ubwo bwoko bubiri bwa putty muri rusange bwo guhitamo cellulose ya methyl yahinduwe na hydroxypropyl methyl ubwoko bubiri bw'ibipimo bya viscosity muri rusange muri 30000-60000cps hagati y'ibikwiriye cyane, muri putty, inshingano nyamukuru ya cellulose ni ugukomeza amazi, gufatanya, amavuta n'izindi nshingano. Kubera ko abakora putty batandukanye ba formula ntabwo ari imwe, zimwe ni calcium y'umukara, calcium yoroheje, sima yera, nibindi, zimwe ni ifu ya gypsum, calcium y'umukara, calcium yoroheje, nibindi, bityo formula ebyiri zo guhitamo ibipimo bya viscosity ya cellulose n'uburyo yinjiramo ingano ntabwo ari imwe, ingano rusange ya 2 ‰ -3 ‰ cyangwa hafi yaho. Mu gusya ibumba ryo ku rukuta, bitewe n’uko ibumba ryo ku rukuta rifite urugero runaka rwo kwinjiza amazi (igipimo cyo kwinjiza amazi ku rukuta rw’amatafari cya 13%, sima kuri 3-5%), hamwe n’isi yo hanze yo guhumeka, bityo iyo ibumba ritakaje amazi vuba cyane, bizatuma habaho icyuho cyangwa gukurwaho ifu n’ibindi bintu, bityo imbaraga za ibumba zigacika intege, kubera iyo mpamvu, nyuma yo kongeramo eteri ya cellulose bizakemura iki kibazo. Ariko ubwiza bw’icyuma cyuzuza, cyane cyane ubwiza bwa kalisiyumu y’umukara nabwo ni ingenzi cyane.

Kubera ko Selulose ifite ubukana bwinshi, bityo no kongera uburyo putty ifatana, ariko kandi hirindwa imiterere yo kumanika, no gukurura nyuma yo koroherwa no kugabanya imirimo n'ibindi. Mu ifu yumye putty cellulose ether igomba kuba ikwiriye kongeramo ingingo nyinshi, umusaruro wayo, ikoreshwa ryayo ni ryoroshye, kuzuza n'ibindi byongerwamo ifu yumye bishobora kuba imvange imwe, kubaka nabyo biroroshye, amazi ari ahantu runaka, hamwe n'ingano yayo hamwe n'ingano yayo.

(2) sima ya beto:

Mu gikoresho cya sima, kigera ku mbaraga za nyuma, kigomba gutuma sima ikomeza kuvura burundu gusa, cyane cyane mu gihe cy'izuba, amazi ya sima atakaza vuba cyane, gifata ingamba zo kuvura burundu mu kubungabunga umuyoboro w'amazi, ubu buryo ni ugupfusha ubusa umutungo w'amazi no kugorana mu mikorere, icy'ingenzi ni uko amazi aba ari hejuru gusa, kandi amazi yo mu nda ntahagije, bityo igisubizo cy'ikibazo cy'uburyo bwo guhuza sima. Selulosi ifata muri rusange hydroxypropyl methyl cyangwa methyl cellulose, imiterere y'ubushyuhe iri hagati ya 20000 - 60000cps, wongereho 2% - 3%. Ahagana, igipimo cyo kubika amazi gishobora kwiyongera kikagera ku kigero kirenga 85%, ikoreshwa rya sima mu buryo bw'ifu yumye ivanze neza mu mazi rishobora kuba.

(3) muri plasta ya stucco, plasta yo guhuza, plasta yometseho:

Bitewe n’iterambere ryihuse ry’inganda z’ubwubatsi, abantu basaba ibikoresho bishya by’ubwubatsi nabyo biriyongera. Bitewe n’ubwiyongere bw’ubumenyi bw’abantu ku kurengera ibidukikije no gukomeza kunoza imikorere y’ubwubatsi, ibikoresho bya gypsum bya sima byatejwe imbere vuba. Kuri ubu, ibikoresho bya gypsum bikunze gukoreshwa cyane ni plaster yo koza, plaster yo koza, plaster yometseho, kole y’amatafari n’ibindi. Plaster yo koza ni ubwoko bw’ibikoresho byiza cyane byo koza ku rukuta rw’imbere n’urubaho rwo hejuru, aho ubuso bw’urukuta buba bworoshye kandi bunoze, nta fu igwa kandi substrate ifatanye neza idacitse cyangwa ngo igwe, kandi ifite akazi ko kwirinda umuriro; plaster yo koza ni ubwoko bushya bw’ibikoresho byo koza ku rukuta by’ubwubatsi, bikozwe muri gypsum nk’ibikoresho by’ibanze kandi byongewemo ibindi bintu bitandukanye, kandi birakwiriye koza ku rukuta rw’ubwoko bwose bw’ibikoresho bidakoresha ikoranabuhanga, bifite imiterere yo kudahumanya, kudakoresha uburyohe, gufungana vuba no kwihuta. Ikwiriye guhuza ubwoko butandukanye bw'ibikoresho by'inkuta z'ubwubatsi bidakoresha umwimerere, bifite uburozi, impumuro, byihuse, bikomera, bifatanye neza n'ibindi bintu, kandi ni ibikoresho byunganira mu kubaka imbaho ​​n'amatafari; gypsum caulk ni icyuma gifunga hagati y'imbaho ​​za gypsum ndetse n'icyuma gisana inkuta n'imiyoboro.

Ibi bicuruzwa bya gypsum bifite urukurikirane rw'imirimo itandukanye, uretse gypsum n'ibindi bifitanye isano bigira uruhare, ikibazo cy'ingenzi ni uko hongerwamo inyongera za eteri za cellulose zigira uruhare runini. Kubera ko gypsum igabanyijemo gypsum idafite amazi na gypsum ifite amazi make, gypsum itandukanye igira ingaruka zitandukanye ku mikorere y'umusaruro, bityo gukomera, kubika amazi no kudindira kw'ibikoresho by'ubwubatsi bya gypsum bigena ubwiza bw'ibikoresho by'ubwubatsi bya gypsum. Ikibazo gikunze kugaragara kuri ibi bikoresho ni ukubohoka no kwangirika, imbaraga za mbere ntizishobora kugerwaho, kugira ngo iki kibazo gikemuke, ni uguhitamo ubwoko bwa cellulose n'uburyo bwo gukoresha ikibazo, muri urwo rwego, guhitamo rusange methyl cyangwa hidroksipropilimetili 30.000 - 60.000cps, ingano yongerwamo ni 1.5% - 2%. Hagati aho, selulosi aho icyibandwaho ni amavuta agabanya amazi. Ariko, muri ibi, gukoresha eteri ya selulosi nk'umusemburo ntibigerwaho, kandi bigomba kongeramo aside citric umusemburo uvanze n'ikoreshwa ryabyo ntibizagira ingaruka ku mbaraga z'ibanze.

Igipimo cyo kubika amazi muri rusange kivuga ku mimerere aho nta mazi yo hanze asohoka, ingano y’amazi atakaye, iyo urukuta rwumye, amazi yo hasi ku buso bw’ubutaka n’amazi atakaye vuba cyane, ibyo bizatera imyobo y’amazi, ibintu bigacika. Ubu buryo bwo gukoresha ifu yumye, niba itegurwa ry’umuti rishobora gusobanura itegurwa ry’umuti.

(4) Sima yo gukingira ubushyuhe

Udupira two gukingira ubushyuhe ni ubwoko bushya bw'ibikoresho byo gukingira imbere mu rukuta, ni ibikoresho byo ku rukuta byakozwe n'ibikoresho byo gukingira ubushyuhe, utwo dupira n'udupira. Cellulose muri iki gikoresho, yibanda ku guhuza, yongera uruhare rw'imbaraga. Muri rusange hitamo selulose ya methyl Ubushyuhe bwinshi (10000cps cyangwa irengaho), igipimo muri rusange kiri hagati ya 2‰-3‰, hakoreshejwe uburyo bwo kuvanga ifu yumye.
