HEC ya matope osakaniza owuma

Chimodzi mwazowonjezera zomwe zimagwiritsidwa ntchito kwambiri mumatope osakaniza ndi hydroxyethyl cellulose (HEC). HEC ndi non-ionic cellulose ether yokhala ndi makulidwe, kusunga madzi, kukhazikika, ndi kuyimitsidwa. Amagwiritsidwa ntchito kwambiri muzomangamanga, makamaka mumatope osakaniza owuma.

1. Udindo wa HEC mu matope osakaniza owuma

Mumatope osakaniza owuma, HEC makamaka imagwira ntchito yosungira madzi, kulimbitsa ndi kupititsa patsogolo ntchito yomanga:

Kusungirako madzi: HEC ili ndi madzi abwino kwambiri osungira madzi ndipo ikhoza kuchepetsa kutaya madzi. Izi ndizofunikira makamaka pamatope osakaniza owuma chifukwa amatalikitsa nthawi yotseguka yamatope, zomwe zimapangitsa ogwira ntchito kusintha matope kwa nthawi yayitali ndikuwongolera ntchito yomanga. Kuonjezera apo, kusunga madzi kungathenso kuchepetsa chiopsezo cha kusweka ndikuonetsetsa kuti ndondomeko yowumitsa matope imakhala yofanana komanso yokhazikika.

Kukhuthala: Kuchulukana kwa HEC kumapangitsa kuti matope azikhala ndi kukhuthala kwabwino, kulola kuti matope amamatire bwino pamwamba pa gawo lapansi pomanga, osati kuterera, komanso kumapangitsa kuti ntchitoyo ikhale yofanana. Mkhalidwe umenewu ndi wofunika kwambiri pomanga moyima ndipo ukhoza kupititsa patsogolo kwambiri mapangidwe a matope.

Limbikitsani ntchito yomanga: HEC imatha kupangitsa matope owuma kukhala osalala komanso osavuta kugwiritsa ntchito, potero amachepetsa zovuta zogwirira ntchito. Zimapangitsa kuti matope azikhala ndi kufalikira kwabwino komanso kumamatira pagawo laling'ono, zomwe zimapangitsa kuti ntchito yomanga ikhale yopulumutsa anthu komanso kuwongolera magwiridwe antchito. Kuphatikiza apo, imathanso kukulitsa luso la anti-sagging, makamaka pakumanga kosanjikiza.

2. Zosankha za HEC

Posankha HEC, zinthu monga kulemera kwake kwa maselo, kuchuluka kwa kulowetsedwa ndi kusungunuka ziyenera kuganiziridwa, zomwe zidzakhudza mwachindunji ntchito ya matope:

Kulemera kwa mamolekyu: Kukula kwa kulemera kwa maselo kumakhudza mphamvu yowonjezereka komanso kusungira madzi kwa HEC. Kawirikawiri, HEC yokhala ndi kulemera kwakukulu kwa maselo imakhala ndi zotsatira zabwino zowonjezera, koma pang'onopang'ono kusungunuka; HEC yokhala ndi mamolekyu ang'onoang'ono imakhala ndi kusungunuka kwachangu komanso kukulitsa pang'ono. Choncho, m'pofunika kusankha molekyulu yoyenera malinga ndi zofunikira za zomangamanga.

Mlingo wolowa m'malo: Kuchuluka kwa kusintha kwa HEC kumatsimikizira kusungunuka kwake ndi kukhazikika kwa mamasukidwe ake. Kukwera kwa digiri ya m'malo, ndikokwanira kusungunuka kwa HEC, koma kukhuthala kudzachepa; pamene mlingo woloweza m'malo uli wotsika, kukhuthala kwake kumakhala kwakukulu, koma kusungunuka kungakhale kosauka. Nthawi zambiri, HEC yokhala ndi m'malo pang'ono ndiyoyenera kugwiritsidwa ntchito mumatope osakanikirana.

Kusungunuka: Kuwonongeka kwa HEC kumakhudza nthawi yokonzekera yomanga. Kwa matope osakaniza owuma, ndi bwino kusankha HEC yomwe imakhala yosavuta kumwazikana ndi kusungunuka mwamsanga kuti ikhale yosinthika yomanga.

3. Kusamala mukamagwiritsa ntchito HEC

Mukamagwiritsa ntchito HEC, muyenera kulabadira kuchuluka kwake komanso momwe mungagwiritsire ntchito kuti muwonetsetse zotsatira zabwino:

Kuwongolera kuchuluka kwa kuchuluka: Kuchulukitsa kwa HEC nthawi zambiri kumayendetsedwa pakati pa 0.1% -0.5% ya kulemera konse kwa matope. Kuonjezera kwambiri kumapangitsa kuti matope akhale ochuluka kwambiri ndipo amakhudza madzi omanga; Kuwonjezera kosakwanira kudzachepetsa mphamvu yosungira madzi. Chifukwa chake, kuyezetsako kuyenera kuchitidwa molingana ndi zosowa zenizeni kuti mudziwe kuchuluka kwake kowonjezera.

Kugwirizana ndi zina zowonjezera: Mumatope osakaniza owuma, HEC nthawi zambiri amagwiritsidwa ntchito pamodzi ndi zowonjezera zina monga redispersible latex powder, cellulose ether, etc. Samalani kugwirizana kwa HEC ndi zosakaniza zina kuti muwonetsetse kuti palibe mkangano ndikukhudzani. zotsatira.

Kusungirako zinthu: HEC ndi hygroscopic, ikulimbikitsidwa kuti isungidwe pamalo owuma ndikupewa kuwala kwa dzuwa. Iyenera kugwiritsidwa ntchito posachedwa mutatha kutsegulidwa kuti mupewe kuwonongeka kwa magwiridwe antchito.

4. Kugwiritsa ntchito kwa HEC

Pogwiritsa ntchito, HEC ikhoza kupititsa patsogolo ntchito yomanga matope owuma komanso kupititsa patsogolo matope. Kukula ndi kusungirako madzi kwa HEC kumapangitsa kuti matope osakaniza owuma akhale omatira bwino komanso okhazikika, zomwe sizimangowonjezera ubwino wa zomangamanga, komanso zimawonjezera nthawi yotseguka ya matope, zomwe zimapangitsa kuti ogwira ntchito azigwira ntchito modekha. Kuonjezera apo, HEC ikhoza kuchepetsa kuchitika kwa kuphulika pamwamba pa matope, kupangitsa matope olimba kukhala olimba komanso okongola.

5. Chitetezo cha chilengedwe ndi chuma cha HEC

HEC ndi yochokera ku cellulose yogwirizana ndi chilengedwe yomwe imatha kuwonongeka komanso kuwononga chilengedwe. Kuphatikiza apo, HEC ndiyotsika mtengo komanso yotsika mtengo, ndikupangitsa kuti ikhale yoyenera kukwezedwa ndikugwiritsa ntchito mitundu yosiyanasiyana ya ntchito zomanga. Kugwiritsiridwa ntchito kwa HEC kungachepetse chiŵerengero cha simenti ya madzi a matope, motero kuchepetsa kumwa madzi, zomwe zimagwirizananso ndi zochitika zamakono zotetezera zachilengedwe zobiriwira m'makampani omangamanga.

Kugwiritsa ntchito HEC mumtondo wosakanizika wowuma kumatha kupititsa patsogolo magwiridwe antchito amatope ndipo ndizofunikira kwambiri pakumanga. Kusungidwa bwino kwa madzi ake, kukhuthala ndi kusinthika kwa zomangamanga kumapangitsa kuti ntchito yomanga ikhale yolimba komanso kuti ikhale yokhazikika. Kusankha

HEC yoyenera ndikuigwiritsa ntchito moyenera sikungangowonjezera luso la zomangamanga, komanso kukwaniritsa chitetezo cha chilengedwe ndi zofunikira zachuma.
