Hydroxypropyl Methylcellulose (HPMC)ndizowonjezera zomangira ndipo zimagwiritsidwa ntchito kwambiri mu putty, zomatira matailosi, zokutira khoma, ndi zina. Kuchita kwake kwakukulu kwathandizira kwambiri guluu womanga wa putty. Nkhaniyi iwunikanso gulu la guluu womanga wa putty kutengera ntchito ya cellulose ya HPMC ndikuwunika momwe msika umafunira komanso momwe chitukuko chikuyendera.
(1) Tanthauzo la guluu womanga
Putty building glue ndi zomatira zomangira zomwe zimagwiritsidwa ntchitokukonza ndi kudzaza malo omangiramonga makoma, kudenga, ndi pansi. Ntchito yake yayikulu ndikupititsa patsogolo kumamatira, madzimadzi, komanso ntchito yomanga ya putty. Pofuna kupititsa patsogolo ntchito yomanga komanso kuuma komaliza kwa putty, zomatira zambiri zomangira zimawonjezera zinthu zina zosinthidwa, monga Hydroxypropyl Methylcellulose (HPMC).
HPMC imagwira ntchito zotsatirazi mu putty:
- Kupititsa patsogolo fluidity:HPMC imatha kusintha bwino madzi a putty slurry, kupanga zomangamanga kukhala zosavuta komanso zosavuta kugwira ntchito.
- Kuwonjezera adhesion:HPMC imatha kupititsa patsogolo mgwirizano pakati pa putty ndi khoma kapena maziko, kuchepetsa kukhetsa ndi kusweka.
- Wonjezerani nthawi yotsegulira:Pambuyo powonjezera HPMC, nthawi yogwiritsira ntchito putty imatha kukulitsidwa, yomwe imathandizira kusintha malo omanga ndikuchepetsa zinyalala zakuthupi.
- Kupewa stratification ndi mpweya:HPMC ilinso ndi kusungirako madzi kwina, komwe kumapewa stratification ndi mpweya wa putty panthawi yosungira ndikugwiritsa ntchito.

(2) Gulu la guluu womanga wa putty
Gulu la guluu womanga wa putty amatha kugawidwa molingana ndi kapangidwe kake, ntchito yake, momwe amagwiritsidwira ntchito, ndi zina. Nthawi zambiri, putty glue akhoza kugawidwa m'magulu awa:
1. Kugawikana mwa kupanga
Guluu wamadzi
Guluu wamadzi ndi mtundu wodziwika kwambiri wa guluu wa putty. Zida zake zoyambira ndi utomoni wosungunuka m'madzi ndi zina zosungunuka m'madzi. Guluu wamadzi ali ndi ubwino wakechitetezo cha chilengedwe, chopanda poizoni, komanso chopanda fungo. Zimakwaniritsa zofunikira za nyumba zobiriwira ndipo ndizoyenera kukongoletsa nyumba, nyumba za anthu, ndi malo ena. HPMC, monga gawo lofunikira la guluu wamadzi, imatha kupititsa patsogolo mphamvu zake zomangira komanso ntchito yomanga.
Guluu wopangidwa ndi zosungunulira
Guluu wosungunulira amagwiritsa ntchito zosungunulira ngati njira yobalalitsira. Ili ndi amkulu kugwirizana mphamvundipo nthawi zambiri imakhala yoyenera kumadera ena apadera omangira, monga madera a chinyezi chambiri. Ngakhale kuti guluu wa zosungunulira amagwiritsidwa ntchito kwambiri, kugwiritsidwa ntchito kwake m’nyumba zamakono n’kochepa chifukwa zosungunulira zake zimatha kuwononga chilengedwe.
2. Gulu ndi ntchito
Guluu wamba wa putty
Guluu wamba wamba ndi woyenera kukonzanso khoma m'nyumba zambiri komanso nyumba zamalonda. Ntchito yake yayikulu ndikuwonjezera kumamatira pakati pa putty ndi maziko oyambira ndikuwongolera ntchito yomanga. Mtengo wa guluuyu nthawi zambiri umakhala wotsika kwambiri ndipo uyenera kugwiritsidwa ntchito pazikuluzikulu.
Guluu wopanda madzi
Guluu wopanda madzi adapangidwa kuti azitha kuthana ndi malo achinyezi kapena ntchito zomanga zomwe zimalumikizidwa mwachindunji ndi madzi, monga mabafa, makhitchini, ndi madera ena. Sikuti imangokhala ndi guluu wamba wa putty, komanso imalepheretsa chinyezi kulowa khoma. Guluu wosalowa madzi nthawi zambiri amawonjezera zina zapadera zosalowa madzi, monga ma emulsion osalowa madzi ndi zida zopangira simenti.
Anti-crack putty guluu
Guluu wa Anti-crack putty amayang'ana vuto la mng'alu lomwe limatha kuchitika pakhoma pakagwiritsidwa ntchito, ndipo limakulitsa kukana kwake kung'ambira kudzera mu utomoni wosinthidwa kapena zowonjezera zotanuka. Guluu wamtundu uwu nthawi zambiri amagwiritsidwa ntchito m'nyumba zomwe zimakhudzidwa mosavuta ndi kusintha kwa kutentha kapena kugwedezeka kwamapangidwe, monga makoma akunja, madenga, ndi mbali zina.

3. Kugawa ndi njira yomanga
Manual kumanga guluu
Guluuyi ndi yoyenera kupangira njira zomangira pamanja, ndipo imayenera kumalizidwa ndi kupaka pamanja, kupaka utoto, ndi zina. Mbali yake yayikulu ndi yotsika mtengo komanso yoyenera kukonzanso pang'ono kapena kukongoletsa.
Makina opopera guluu
Guluu wopopera wamakina amagwiritsidwa ntchito makamaka pantchito zomanga zazikulu, makamaka nyumba zazitali zomwe zimafunikira zokutira zambiri za putty. Kugwiritsa ntchito zida zopopera pomanga sikungangowonjezera luso la zomangamanga, komanso kuonetsetsa kuti guluu likugawidwa mofanana komanso kuchepetsa zinyalala.
4. Gulu ndi zowonjezera
Guluu wamba wa putty
Guluu wamtunduwu umagwiritsa ntchito zowonjezera zanthawi zonse ndipo ndizoyenera kumanga khoma. HPMC amatenga mbali yofunika mmenemo, kusintha fluidity ndi operability.
Guluu wosinthidwa wa putty
Guluu wa Modified putty adzawonjezera zina zapadera za mankhwala, monga ma polima emulsion, elastomers, ndi zina zotero.adhesion, elasticity ndi nyengo kukanaza guluu, ndipo ndizoyenera makamaka pantchito zomanga zofunidwa kwambiri.

(3) Kufuna kwa msika ndi chitukuko
Ndikukula kwachangu kwamakampani omanga, kufunikira kwa guluu womanga wa putty kukukulirakulira. Makamaka pankhani yazovuta zomwe zikufunika kuteteza chilengedwe,Guluu wothira madzi pang'onopang'ono wakhala msika waukulu kwambiri. Pofuna kukwaniritsa kufunikira kwa msika, ambiri opanga ma cellulose a HPMC akuwonjezera zoyesayesa zawo za R&D kulimbikitsa luso laukadaulo la guluu womanga wa putty. Mwachitsanzo, opanga ambiri akuyamba kupangalow-VOC (volatile organic compounds) kapena zomatira za VOC zopanda chilengedwekukwaniritsa zofunikira za nyumba zobiriwira.
Ndi kupita patsogolo kwa ukadaulo womanga, ukadaulo wopopera mbewu mankhwalawa umayambanso kukhala chizolowezi. Njirayi sikuti imangowonjezera luso la zomangamanga, komanso imachepetsa kufunika kwa anthu ogwira ntchito, choncho imagwiritsidwa ntchito kwambiri m'nyumba zokwera, nyumba zamalonda, ndi madera ena.
Gulu la guluu womanga wa putty amagawidwa molingana ndi miyeso yosiyanasiyana monga kapangidwe, ntchito, ndi njira yomanga. Monga chowonjezera chofunikira,Mtengo wa HPMCamatenga gawo lofunikira pakuwongolera magwiridwe antchito, ntchito yomanga, komanso kumamatira kwa putty glue. Pakuchulukirachulukira kwa zida zomangira zokondera komanso zogwira ntchito kwambiri pamsika womanga, guluu yomanga ya putty ipitilira kutukuka ndikukula m'njira yobiriwira, yosamalira zachilengedwe, komanso njira yabwino. Opanga ma cellulose a HPMC amatenga gawo lofunikira kwambiri pakuchita izi, ndipo kupanga kwawo kwazinthu zatsopano komanso chitukuko chaukadaulo chidzakhudza momwe msika wonse ukuyendera.
