Zotsatira za cellulose ether pa pulasitiki

1. Kafukufuku wamtundu wacellulose etherPa shrink frop ya matope matope

Matope ndi nkhani yogwiritsidwa ntchito kwambiri pantchito zomanga, ndipo kukhazikika kwa ntchito yake kumakhala ndi kofunikira pa nyumba. Ma shromenor aulere ndi chodabwitsa chomwe chingachitike m'matope asanavutike, chomwe chingayambitse mavuto monga ming'alu m'matope, akukhudza kulimba kwake komanso zolimbitsa. Cellulose ether, monga zowonjezera wamba mu matope, zimakhala ndi zofunika pa matope a matope apulasitiki.

2. Mfundo ya cellulose ether ether imachepetsa mafilimu aulere a matope

Cellulose ether ili ndi madzi abwino kwambiri. Kutayika kwamadzi mu matope ndi chinthu chofunikira chotsogolera ku shlizani pulasitiki zaulere. Magulu a hydroxyl pa cellulose ether mamolekyulu ndi oxygen zomangira za ether zimapanga ma mamolekyulu a hydrogen, kutembenuza madzi osalowa m'madzi omanga, motero amachepetsa kuchepa kwa madzi. Mwachitsanzo, mu maphunziro ena, zinapezeka kuti ndi kuchuluka kwa mlingo wa ethel ether, kuchuluka kwa madzi mu matope kunachepa. NgatiMethyl hydroxypropyl cellulose ether (hpmc), pamene Mlingo ndi 0.1-0.4 (chidutswa cha misa), limatha kuchepetsa kutaya kwamadzi kwa simenti ndi 9-29%.

Cellulose ether imathandizira kukhala ndi ziphuphu, kapangidwe kake ndi mafuta osmotic cha mmenga watsopano, ndipo katundu wake wopanga mafilimu amalepheretsa kusokonekera kwa madzi. Mitundu yosiyanasiyana iyi yolumikizira nkhawa yomwe imapangidwa ndi zosintha chinyezi m'matope, potero poletsa pulasitiki aulele.

3. Mphamvu ya cellulose mlingo pa pulasitiki yaulere ya matope

Kafukufuku wawonetsa kuti mafola apulasitiki aulere a simenti amachepetsa kuzungulira ndi kuchuluka kwa maselo a ether. Kutenga HPMC monga chitsanzo, pomwe Mlingo ndi 0.1-0.4 (chidutswa cha madontho), matope aulere a simenti amatha kuchepetsedwa ndi 30-50%. Izi ndichifukwa choti pamene mankhwalawa amawonjezeka, madzi ake osasunga ndi matenda ena oletsa kuperewera.

Komabe, mlingo wa ethel ether sungachuluke mpaka kalekale. Kumbali ina, kuchokera pazachuma, kuphatikiza kwambiri kudzakulitsa mtengo; Kumbali inayo, cellulose yambiri ether imatha kukhala ndi vuto lina la matope, monga mphamvu ya matope.

4. Kutanthauza kukopa kwa cellulose ether papulasitiki

Kuchokera panjira yothandizana ndi ntchito yopanga, kuwongolera koyenera kwa cellulose kwa matope kumatha kuchepetsa matendawa aulere, potero kuchepetsa kupezeka kwa matope. Izi ndizofunikira kwambiri kuti zithetse nyumba zamtundu, makamaka kuti zitheke kukhazikika kwa nyumba monga makhoma.

Mu ntchito zina zapadera zokhudzana ndi matope, monga nyumba zina zomaliza zokhala ndi matope komanso zomangira zam'madzi zam'madzi pa matope, zitha kutsimikiziridwa kuti polojekiti yapamwamba .

5.

Ngakhale kuti pakhala kufufuza kwina kwakhala ndi zotsatira za ether ether pa matope aulere a matoputala, pali zinthu zambiri zomwe zingawonjezereko mozama. Mwachitsanzo, kukopa mitundu yosiyanasiyana ya cellulose etrase pa matope a matopu apulasitiki akamachita limodzi ndi zina zowonjezera.

Ndi chitukuko chopitilira muukadaulo chomanga, zofuna za matope zimachulukirachulukirachulukira. Kafukufuku wina amafunikirabe kuwongolera momwe mungachitire molondola kugwiritsa ntchito kwa cellulose ku matope kuti akwaniritse zabwino zothetsa matendawa pomwe akugwiritsa ntchito zida zina za matope.
