Cellulose ether ndi organic pawiri ndi ntchito yabwino, amene chimagwiritsidwa ntchito m'munda wa zipangizo zomangamanga, makamaka pokonzekera ndondomeko ya khoma putty ndi mkati ndi kunja khoma putty. Sizingangowonjezera bwino ntchito yomanga ya putty, komanso kupititsa patsogolo kulimba ndi mphamvu ya putty pambuyo pa ntchito.
1. Chidule cha cellulose ether
Ma cellulose ether ndi gulu la ma polima osungunuka m'madzi kapena osabalalika m'madzi opangidwa ndi kusinthidwa kwamankhwala kutengera mapadi achilengedwe. Ma cellulose ethers odziwika bwino akuphatikizapo hydroxypropyl methylcellulose (HPMC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), etc. Ma cellulose ethers amakhala ndi kukhuthala bwino, kusunga madzi, kudzoza, kupanga mafilimu ndi zinthu zina, kotero amagwiritsidwa ntchito kwambiri pomanga. zipangizo.
2. Udindo wa cellulose ether mu putty
Kupititsa patsogolo ntchito yomanga ya putty
Ma cellulose ether amawongolera mawonekedwe a rheological a putty, kuti magwiridwe antchito ndi kusanja kwa putty athe kuwongolera, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito komanso mulingo. Makamaka pakumanga kwakukulu, kukhuthala kwa cellulose ether kumatha kupanga putty kumamatira khoma, kuchepetsa kugwa, ndikuwonetsetsa kukhazikika kwa zomangamanga.
Konzani kasungidwe ka madzi
Putty wosanjikiza amafunika kukhala wonyowa pang'ono panthawi yomanga kuti atsimikizire kufanana ndi kumamatira kwa kuyanika kotsatira. Ma cellulose etha mamolekyu amatha kuyamwa madzi ochulukirapo ndikupanga maukonde a molekyulu yamadzi mu putty, kumachepetsa kuchuluka kwa evaporation yamadzi a putty, potero kuwongolera kusungika kwamadzi kwa putty. Kusungidwa kwamadzi kumeneku kumapangitsa kuti putty asakhale wosweka kapena ufa akamamangidwa pansi pa kutentha kwambiri kapena kowuma, kumatalikitsa nthawi yomanga ndikuwonetsetsa kuti gawo la putty likuyenda bwino.
Wonjezerani mphamvu ya mgwirizano
Kuchulukitsa zomwe zili mu cellulose ether kumatha kupititsa patsogolo kumamatira kwa putty ndikuwonetsetsa kuti putty imangiriridwa pamwamba pa maziko. Putty ikagwiritsidwa ntchito, ether ya cellulose sikuti imangowonjezera kulimba kwa putty, komanso imaperekanso kuchuluka kwa zomatira panthawi yowumitsa kuti zisanjidwe za putty zisagwe kapena kugwa. Izi ndizofunikira makamaka pa malo osalala komanso zoyambira zopanda mayamwidwe chifukwa cellulose ether imapereka zowonjezera zowonjezera.
Yesetsani kuyanika liwiro
Ma cellulose ether amatha kusintha liwiro la kuyanika kwa putty kuti gawo la putty liwume mofanana, potero kupewa kusweka komwe kumachitika chifukwa cha kutayika kwamadzi mwachangu pamtunda. Popanga ma putty angapo osanjikiza, kuthamanga koyenera kuyanika ndikofunikira kwambiri, komwe kumathandizira kutsimikizira kumamatira pakati pa zigawo ndi zotsatira zake zonse.
Sinthani magwiridwe antchito a anti-sagging
M'makoma oyima kapena kudenga, putty imakhudzidwa mosavuta ndi mphamvu yokoka ndipo imakhala ndi vuto la kugwa ndi kugwa. Kukhuthala kwa cellulose ether kumatha kupititsa patsogolo kukhuthala ndi kukhazikika kwa putty, kuteteza zinthu kuti zisagwere chifukwa cha mphamvu yokoka, ndikuwonetsetsa kugawa kofanana kwa putty.
3. Mitundu yayikulu ndi kusankha ma cellulose ethers
Mitundu yosiyanasiyana ya ma cellulose ether imakhala ndi zotsatira zosiyana mu putty, ndipo ndikofunikira kwambiri kusankha mtundu woyenera wa cellulose ether. Zotsatirazi ndi zingapo zomwe zimagwiritsidwa ntchito pa cellulose ethers ndi mawonekedwe awo:
Hydroxypropyl methylcellulose (HPMC): Ili ndi kukhuthala bwino, kusunga madzi komanso kupanga mafilimu ndipo imagwiritsidwa ntchito kwambiri pomanga putty. HPMC imatha kusintha kwambiri mapangidwe ndi kupanga mafilimu a putty, kupanga putty kukhala yosalala ikagwiritsidwa ntchito, ndikuwongolera kumamatira ndi kusalala kwa putty.
Hydroxyethyl cellulose (HEC): Imagwiritsidwa ntchito makamaka m'makina otengera madzi, imakhala ndi mphamvu zowongola bwino za kukhuthala ndi rheology, ndipo nthawi zambiri imagwiritsidwa ntchito mkati mwa khoma lamkati ndi zokutira zokhala ndi madzi. HEC imakhala ndi kusintha kwakukulu pakuyika kwa putty, koma kusunga kwake madzi ndikotsika pang'ono poyerekeza ndi HPMC.
Hydroxypropyl cellulose (HPC): HPC ili ndi kukhuthala kwakukulu komanso kukhazikika kwabwino kwambiri, ndipo ndiyoyenera nthawi zomwe zimakhala ndi zofunika kwambiri polimbana ndi kugwa. Kuwonjezera kuchuluka koyenera kwa HPC ku putty kumatha kupititsa patsogolo magwiridwe antchito a anti-sagging komanso mphamvu ya putty.
4. Ubwino wogwiritsa ntchito ndi chiyembekezo cha msika wa ma cellulose ethers
Ubwino wogwiritsa ntchito ma cellulose ethers mu putty ndiwofunikira, makamaka akuwonetsedwa muzinthu izi:
Kupulumutsa mtengo: Ma cellulose ether amatha kupititsa patsogolo magwiridwe antchito a putty, kuchepetsa kuchuluka kwa kukonzanso, motero kuchepetsa ndalama zakuthupi ndi ntchito.
Chitetezo cha chilengedwe: Ma cellulose ethers ndi zinthu zachilengedwe zopangidwa kuchokera kuzinthu zowonjezereka, zotetezedwa bwino ndi chilengedwe, zopanda poizoni kwa thupi la munthu, ndikuthandizira kukwaniritsa zofunikira za zipangizo zamakono zopangira chitetezo cha chilengedwe chobiriwira.
Kugwirizana ndi nyengo zosiyanasiyana: Kusungidwa kwa madzi ndi kukana kwa ming'alu ya cellulose ethers kumapangitsa kuti ikhale yoyenera kumanga pansi pa nyengo zosiyanasiyana, kukwaniritsa zosowa za malo osiyanasiyana omanga monga kumpoto kouma ndi kumwera kwa chinyezi.
Chiyembekezo chabwino chamsika: Chifukwa chakukula kwa nyumba zobiriwira komanso kufunikira kwa zida zomangira zogwira ntchito kwambiri, kufunikira kwa msika wama cellulose ethers monga zowonjezera zowonjezera kukukulirakulira chaka ndi chaka. Makamaka m'makampani okongoletsera, zofunikira pakubisala kwa khoma ndi kukongola kwapamwamba zasinthidwa, zomwe zakulitsa malo opangira zinthu za putty. Cellulose ether monga chosinthira adzakhala ndi chiyembekezo chokulirapo chogwiritsa ntchito.
5. Chenjezo la cellulose ether mu ntchito ya putty
Ngakhale cellulose ether ili ndi zabwino zambiri mu putty, mfundo zotsatirazi ziyenera kuzindikirika munjira yeniyeni yogwiritsira ntchito:
Kuwongolera Mlingo: Kuwonjezera kwambiri kwa cellulose ether kumabweretsa kukhuthala kochuluka kwa putty ndikusokoneza momwe ntchito yomanga imapangidwira. Choncho, kuchuluka kwa ether ya cellulose yomwe yawonjezeredwa mu ndondomeko ya putty iyenera kuyendetsedwa moyenera kuti zitsimikizidwe kuti ntchito yomanga imayenda bwino.
Kubalalika kofanana: Kubalalitsidwa kwa cellulose ether mu putty kumakhudza mwachindunji zotsatira zake. Pofuna kupewa kuphatikizika kwa cellulose ether, ndikofunikira kutengera njira zokondoweza zoyenera pokonzekera putty kuti zitsimikizire kuti zimabalalika m'madzi.
Kugwirizana ndi zina zowonjezera: Mapangidwe a putty nthawi zambiri amakhala ndi zowonjezera zina, monga redispersible latex powder, fillers, etc. Kugwirizana kwa cellulose ether ndi zowonjezera izi kudzakhudza mwachindunji ntchito ya putty, kotero kugwirizana pakati pa zosakaniza zosiyanasiyana kuyenera kuganiziridwa mokwanira popanga. ndondomeko.
Kuyika kwa cellulose ether mu khoma la putty ndi putty sikumangowonjezera kamangidwe ndi kagwiritsidwe ka putty, komanso kumakulitsa moyo wautumiki wa putty ndikuchepetsa mavuto omwe amayamba chifukwa chomanga molakwika. Ndi kukula kosalekeza kwa msika wobiriwira ndi zokongoletsa, cellulose ether, ngati chowonjezera chothandiza pachilengedwe komanso chothandiza, chili ndi chiyembekezo chogwiritsa ntchito. M'mapangidwe a putty formula, kusankha koyenera ndi kugwiritsa ntchito cellulose ether kungapereke kukhazikika koyenera komanso kukhazikika kwa makoma omanga, potero kukwaniritsa nyengo zosiyanasiyana ndi zofunikira zomanga, ndikupereka zitsimikizo zolimba za chitukuko chapamwamba cha nyumba zamakono.
