Putty ndi pulasitala ndi zida zofunika pomanga, zomwe zimagwiritsidwa ntchito popanga malo osalala ndikuwonetsetsa kuti mamangidwe azikhala okhazikika. Kuchita kwa zipangizozi kumakhudzidwa kwambiri ndi zomwe zimapangidwira komanso zowonjezera zomwe zimagwiritsidwa ntchito. Methyl Hydroxyethyl Cellulose (MHEC) ndiye chowonjezera chofunikira pakuwongolera komanso magwiridwe antchito a putty ndi pulasitala.
Kumvetsetsa Methyl Hydroxyethyl Cellulose (MHEC)
MHEC ndi ether ya cellulose yochokera ku cellulose yachilengedwe, yosinthidwa kudzera mu methylation ndi hydroxyethylation process. Kusintha kumeneku kumapereka kusungunuka kwamadzi ndi zinthu zosiyanasiyana zogwirira ntchito ku cellulose, kupangitsa MHEC kukhala chowonjezera chosunthika muzomangamanga.
Chemical Properties:
MHEC imadziwika ndi kuthekera kwake kupanga njira yothetsera viscous ikasungunuka m'madzi.
Ili ndi luso lapamwamba lopanga filimu, yopereka chitetezo chomwe chimapangitsa kulimba kwa putty ndi pulasitala.
Katundu Wathupi:
Zimawonjezera kusungidwa kwa madzi kwa zinthu zopangidwa ndi simenti, zomwe zimafunikira kuchiritsa koyenera komanso kukulitsa mphamvu.
MHEC imapereka thixotropy, yomwe imapangitsa kuti ntchito ikhale yosavuta komanso yosavuta kugwiritsa ntchito putty ndi pulasitala.
Udindo wa MHEC ku Putty
Putty imagwiritsidwa ntchito kudzaza zolakwika zazing'ono pamakoma ndi madenga, zomwe zimapereka malo osalala kuti azijambula. Kuphatikizidwa kwa MHEC mu ma putty formulations kumapereka maubwino angapo:
Kuchita Bwino Kwabwino:
MHEC imathandizira kufalikira kwa putty, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikufalikira pang'ono komanso molingana.
Makhalidwe ake a thixotropic amalola kuti putty akhalebe m'malo atatha kugwiritsa ntchito popanda kugwedezeka.
Kusunga Madzi Kwambiri:
Posunga madzi, MHEC imatsimikizira kuti putty imakhalabe yogwira ntchito kwa nthawi yayitali, kuchepetsa chiopsezo cha kuyanika msanga.
Nthawi yowonjezereka yogwirira ntchito iyi imalola kusintha kwabwinoko ndikusalaza pakugwiritsa ntchito.
Kumamatira Kwambiri:
MHEC imathandizira zomatira za putty, kuwonetsetsa kuti zimamamatira ku magawo osiyanasiyana monga konkriti, gypsum, ndi njerwa.
Kumamatira kowonjezera kumachepetsa kuthekera kwa ming'alu ndi kutsekeka pakapita nthawi.
Kuchulukitsa Kukhalitsa:
Kuthekera kopanga filimu kwa MHEC kumapanga chotchinga choteteza chomwe chimapangitsa kulimba kwa putty layer.
Chotchinga ichi chimateteza pansi ku chinyezi ndi zinthu zachilengedwe, kumatalikitsa moyo wa putty application.
Udindo wa MHEC mu Plaster
Pulasita imagwiritsidwa ntchito popanga malo osalala, olimba pamakoma ndi madenga, nthawi zambiri ngati maziko omaliza ntchito. Ubwino wa MHEC pakupanga pulasitala ndiwofunika:
Kukhazikika Kwabwino ndi Kugwira Ntchito:
MHEC imasintha rheology ya pulasitala, kuti ikhale yosavuta kusakaniza ndikuyika.
Amapereka mawonekedwe osasinthasintha, okoma omwe amathandizira kugwiritsa ntchito bwino popanda zotupa.
Kusunga Madzi Kwambiri:
Kuchiritsa bwino kwa pulasitala kumafuna kusunga chinyezi chokwanira. MHEC imawonetsetsa kuti pulasitala imasunga madzi kwa nthawi yayitali, zomwe zimapangitsa kuti tinthu tating'ono ta simenti tizitha.
Kuchiritsa kotereku kumapangitsa kuti pulasitala ikhale yamphamvu komanso yolimba.
Kuchepetsa ming'alu:
Polamulira kuchuluka kwa kuyanika, MHEC imachepetsa chiopsezo cha ming'alu ya shrinkage yomwe ingachitike ngati pulasitala iuma mofulumira kwambiri.
Izi zimapangitsa kuti pakhale pulasitala yokhazikika komanso yofananira.
Kulumikizana Kwabwino ndi Kugwirizana:
MHEC imathandizira zomatira za pulasitala, kuonetsetsa kuti zimalumikizana bwino ndi magawo osiyanasiyana.
Kulumikizana kolimba mkati mwa pulasitala kumapangitsa kuti ikhale yolimba komanso yokhalitsa.
Njira Zowonjezera Zochita
Kusintha kwa Viscosity:
MHEC imawonjezera kukhuthala kwa mayankho amadzimadzi, omwe ndi ofunikira kwambiri pakusunga bata ndi homogeneity ya putty ndi pulasitala.
Kukula kwamphamvu kwa MHEC kumatsimikizira kuti zosakanizazo zimakhalabe zokhazikika panthawi yosungiramo ndikugwiritsa ntchito, kuteteza kugawanika kwa zigawo.
Kuwongolera kwa Rheology:
The thixotropic chikhalidwe cha MHEC zikutanthauza kuti putty ndi pulasitala amasonyeza kukameta ubweya-kupatulira khalidwe, kukhala zochepa viscous pansi kukameta ubweya nkhawa (pa ntchito) ndi kubwezeretsa mamasukidwe akayendedwe akapuma.
Katunduyu amalola kugwiritsa ntchito mosavuta ndikusintha zida, ndikutsatiridwa ndikukhazikitsa mwachangu popanda kugwa.
Kupanga Mafilimu:
MHEC imapanga filimu yosinthika komanso yosalekeza poyanika, zomwe zimawonjezera mphamvu zamakina ndi kukana kwa putty ndi pulasitala.
Kanemayu amakhala ngati chotchinga motsutsana ndi zinthu zachilengedwe monga chinyezi komanso kutentha kwamitundu yosiyanasiyana, kukulitsa moyo wautali wakumapeto.
Zopindulitsa Zachilengedwe ndi Zachuma
Sustainable Additive:
Kuchokera ku cellulose yachilengedwe, MHEC ndi chowonjezera chosawonongeka komanso chosawononga chilengedwe.
Kugwiritsiridwa ntchito kwake kumathandizira kuti zipangizo zomangira zikhale zokhazikika pochepetsa kufunikira kwa zowonjezera zowonjezera komanso kupititsa patsogolo ntchito ya zinthu zachilengedwe.
Mtengo:
Kuchita bwino kwa MHEC pakuwongolera magwiridwe antchito a putty ndi pulasitala kumatha kubweretsa kupulumutsa ndalama pakapita nthawi.
Kukhazikika kokhazikika komanso kuchepetsedwa zofunika pakukonza kumachepetsa mtengo wonse wokhudzana ndi kukonzanso ndikugwiritsanso ntchito.
Mphamvu Zamagetsi:
Kusungidwa bwino kwa madzi ndi kugwirira ntchito kumachepetsa kufunika kosakanikirana pafupipafupi ndikusintha kagwiritsidwe ntchito, kupulumutsa mphamvu ndi ndalama zogwirira ntchito.
Njira yabwino yochiritsira yomwe imayendetsedwa ndi MHEC imatsimikizira kuti zidazo zimapeza mphamvu zambiri ndi mphamvu zochepa.
Methyl Hydroxyethyl Cellulose (MHEC) ndiwowonjezera wofunikira pakukhathamiritsa kwa putty ndi pulasitala. Kuthekera kwake kukulitsa magwiridwe antchito, kusunga madzi, kumamatira, komanso kulimba kumapangitsa kuti ikhale yofunika kwambiri pakumanga kwamakono. Pakuwongolera kusasinthika, mawonekedwe ogwiritsira ntchito, komanso mtundu wonse wa putty ndi pulasitala, MHEC imathandizira pakumanga koyenera komanso kokhazikika. Ubwino wake wa chilengedwe komanso kutsika mtengo kwake kumalimbitsanso ntchito yake monga chinthu chofunikira kwambiri pomanga. Pamene ntchito yomanga ikupitabe patsogolo, kugwiritsa ntchito MHEC popanga ma putty ndi pulasitala kukuyembekezeka kufalikira kwambiri, ndikupititsa patsogolo luso la zomangamanga ndi luso.
