HPMC (Hydroxypropyl Methyl Cellulose) ndi ether ya cellulose yomwe ikukula kwambiri pantchito yomanga monga chowonjezera ku putty.Skim coat ndikugwiritsa ntchito simenti yopyapyala pamalo owoneka bwino kuti isalala bwino komanso kuti ikhale yowonjezereka.Apa tikuwunika maubwino ogwiritsira ntchito HPMC muzovala zoyera.
Choyamba, HPMC imagwira ntchito ngati humectant, zomwe zikutanthauza kuti zimathandiza kuti skim layer ikhale yonyowa.Zimenezi n’zofunika chifukwa zinthu zikauma msanga, zimatha kung’ambika kapena kucheperachepera, zomwe zimapangitsa kuti pakhale malo osafanana.Powonjezera nthawi yowumitsa, HPMC ikhoza kuthandizira kuti malaya osambira aziuma mofanana, zomwe zimapangitsa kuti zikhale zosalala, zowoneka bwino.
Chachiwiri, HPMC imagwiranso ntchito ngati thickener, zomwe zikutanthauza kuti zingathandize kuonjezera kukhuthala kwa putty.Izi ndizofunikira makamaka mukamagwira ntchito ndi zida zoonda kapena zopindika, chifukwa zimatha kuteteza kudontha ndikuwonetsetsa kuti zinthuzo zimamatira bwino.Powonjezera kusasinthasintha kwa putty wosanjikiza, HPMC ingathandizenso kuchepetsa mwayi wa matumba a mpweya kupanga zinthu, zomwe zingayambitse ming'alu ndi zolakwika zina.
Phindu lina la HPMC ndikuti lingathandize kukonza machinability a putty.Izi ndichifukwa choti imagwira ntchito ngati mafuta, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito zinthuzo ndikuwonetsetsa kuti zinthuzo zigawika bwino padziko lonse lapansi.Mwa kukonza makina, HPMC imatha kupulumutsa nthawi ndi mphamvu panthawi yogwiritsira ntchito, ndikupangitsa kukhala chisankho chodziwika bwino kwa makontrakitala ndi okonda DIY.
Kuphatikiza apo, HPMC imagwirizana kwambiri ndi zowonjezera zina zomwe zimagwiritsidwa ntchito kwambiri mu ma varnish, monga latex ndi acrylic binders.Izi zikutanthauza kuti zitha kugwiritsidwa ntchito limodzi ndi zidazi kuti zikwaniritse magwiridwe antchito enieni, monga kumamatira bwino kapena kukana madzi.Mwa kupititsa patsogolo magwiridwe antchito onse a ma putty, HPMC imatha kuthandizira kukulitsa moyo wa malo omalizidwa ndikuchepetsa kufunika kokonzanso kapena kukonzanso kokwera mtengo.
Ubwino wa chilengedwe pogwiritsa ntchito HPMC ndiwofunikanso kutchulidwa.Monga polima wachilengedwe wopangidwa kuchokera ku cellulose, ndi biodegradable komanso sipoizoni, kupangitsa kuti ikhale yotetezeka komanso yokhazikika m'malo opangira zowonjezera.Kuonjezera apo, popeza ndi madzi osungunuka, palibe chiopsezo chowononga madzi apansi kapena machitidwe ena amadzi panthawi yogwiritsira ntchito kapena kuyeretsa.
Pomaliza, HPMC ndi chowonjezera chogwira ntchito komanso chothandiza cha putty chokhala ndi maubwino angapo posunga madzi, kukhuthala, kumanga, kuyanjana ndi kukhazikika.Pophatikizira HPMC m'zinthu zawo zokutira, makontrakitala ndi ma DIYers atha kukhala osalala, owoneka bwino komanso okhazikika komanso olimba.
