Cellulose ether, yomwe imadziwikanso kuti methyllulose / hydroxypropylmethylfuloulose (hpmc / Mithec), ndi polymer yosungunuka yomwe imagwiritsidwa ntchito pomanga. Ili ndi malo angapo ofunikira omwe amapangitsa kuti kukhala zinthu zofunika kwambiri za matope ndi simenti. Malo apadera a celluloses ether amaphatikizapo kusungidwa kwamadzi, kutsatira kwabwino, komanso kuthekera kochita ngati olimira.
Cellulose ers zimawonjezera mphamvu ya matope mwa kupereka kusinthasintha komanso kutulutsidwa kwa matole. Zotsatira zake, zinthuzo zimakhala zosavuta kugwira ntchito ndipo zomaliza ndizokhazikika. Nkhaniyi ifotokoza za momwe celluulose edde (hpmc / michec) zimakhudza luso la matope.
Zotsatira za cellulose ether pa matope
Cellulose eds ndi zofunikira zazikulu mu zinthu zambiri zomanga, kuphatikizapo matope ndi simenti. Mukamagwiritsa ntchito matope, ma cellulose eyather imagwira ntchito ngati bander, kuthandiza kumangirira kusakaniza ndikuwonjezera kugwiritsidwa ntchito kwa nkhaniyo. Katundu wosunga madzi wa celluse amapereka malo abwino kuti azichiritsa mankhusu ndi simenti, pomwe kutsatira bwino kumathandiza kuti apange mgwirizano wolimba pakati pa zinthu zosiyanasiyana.
Matope ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito popindika njerwa kapena midadada. Mtundu wa zomangira umakhudza mphamvu ndi kulimba kwa kapangidwe kake. Kuphatikiza apo, mphamvu zolimba ndi katundu wofunikira kuti utsimikizire kuti mawonekedwe amatha kupirira zonse zomwe zimagonjetsedwa. Mphamvu zolimba za matope ndizofunikira kwambiri chifukwa kapangidwe kake ndi kupsinjika kapena katundu kumadalira kwambiri pa luso la matope. Ngati mphamvu ya bonda siyikukwanira, kapangidwe kake kamakhala ndi mavuto akulu monga kusokonekera kapena kulephera, zomwe zimapangitsa kuti pakhale ngozi zosayembekezereka, kuchuluka kwa ndalama zosungidwa ndi ngozi zotetezeka.
Makina ogwiritsira ntchito cellulose et
Cellulose ether ndi polymer osungunuka madzi omwe amagwiritsidwa ntchito kukonza matope. Njira yogwiritsira ntchito ma cellulose mu matope ndi kubalalitsa kwa zowonjezera, zomwe zimayenera kukhala osungunuka osungunuka madzi, ndikuwonjezera mphamvu ya zida pochepetsa nkhawa za zinthuzo. Izi zikutanthauza kuti nthawi ya cellulose ether imawonjezedwa ndi matope, imabalalika nthawi yonseyi, kupewa mapangidwe a zotupa zomwe zingayambitse mawanga ofooka mu mgwirizano wa matontho.
Cellulose mul Kuphatikiza apo, zimathandizira voliyumu ya mpweya ndikuwonjezera kugwirira ntchito kwa matope chifukwa champhamvu kwambiri komanso kuchuluka kwa kugwiritsa ntchito. Cellulose yowonjezera ku chivundi imachepetsa mtengo womwe madziwo mwa osakaniza amatuluka, kupangitsa kuti matontho azikhala osavuta kugwiritsira ntchito ndi kugwirizira zigawo mwamphamvu.
Ubwino wa cellulose ether pamatope
Kuphatikiza kwa cellulose et (hpmc / michec) kwa matope ali ndi phindu lililonse kuphatikizapo mphamvu yolimbikitsani. Mphamvu zapamwamba zimachulukitsa kulimba kwazinthu zazitali za kapangidwe kake, kupewa kukonza ndalama.
Te cellulose eners zimaperekanso kugwirira ntchito kwa matope, ndikupangitsa kukhala kosavuta kumanga ndikuchepetsa nthawi yofunikira ntchito yogwira ntchito. Kugwiritsa ntchito bwino kumeneku kumathandizira kuwonjezera liwiro ndi kuchita bwino, potero kukulira zokolola m'makampani omanga.
Cellulose ether imatha kukonzanso matoputala amadzi ndikuwonetsetsa nthawi yokwanira kuchiritsa. Izi zimawonjezera kugwirizanitsa kwa zinthu zomwe zimagwiritsidwa ntchito pomanga, zomwe zimapangitsa kukhala kokhazikika.
Matope a cellulose owonjezera amakhala osavuta kuyeretsa, ndikuchotsa zowonjezera kuchokera mnyumba yomalizidwa sikovuta. Kuchulukitsa kwa matope ku zinthu zomangamanga kumatanthauza kuwonongeka kocheperako chifukwa kusakaniza sikungatulutse kapena kumasula kuchokera ku kapangidwe kake pamapangidwe.
Pomaliza
Kuphatikiza kwa cellulose endo (hpmc / mathec) kwa matope amatenga gawo lofunikira pakuwongolera mphamvu ya matope a matope a zomangamanga. Cellulose amapereka chisungiko chamadzi, kusintha kugwiritsidwa ntchito kwa matope, ndikulola pang'ono pang'onopang'ono kugwirira ntchito bwino. Kuchuluka kwa mgwirizano kumatsimikizira kulimba kwa kapangidwe kake, ndikuchepetsa zovuta za anthu osayembekezereka, kusintha chitetezo ndikuchepetsa ndalama zomangira. Poganizira zabwino zonse izi, zikuwonekeratu kuti kugwiritsa ntchito cellulose kuyenera kukhala opangidwa bwino m'makampani omanga abwino komanso olimbikitsa.
