Wall putty ke karolo ea bohlokoa ea mokhoa oa ho penta.Ke motsoako oa li-binders, li-filler, li-pigments le li-additives tse fanang ka bokaholimo bo boreleli.Leha ho le joalo, nakong ea kaho ea putty ea lerako, mathata a mang a tloaelehileng a ka 'na a hlaha, a kang ho senya, ho foam, joalo-joalo.Litaba tsena ka bobeli li ka ama ponahalo ea ho qetela ea marako a pentiloeng.Leha ho le joalo, ho na le tharollo mathateng ana - sebelisa HPMC ka putty leboteng.
HPMC e emetse hydroxypropyl methylcellulose.Ke kompone e sebelisoang haholo liindastering tse fapaneng ho kenyeletsoa kaho.HPMC ke tlatsetso e loketseng bakeng sa putties ea lebota kaha e ntlafatsa ts'ebetso, momahano le matla a motsoako.O mong oa melemo ea bohlokoa ea ho sebelisa HPMC ke bokhoni ba ho fokotsa ho tsoa le ho phatloha.Mona ke tlhaloso ea hore na HPMC e ka thusa joang ho felisa mathata ana:

Deburring ke bothata bo tloaelehileng ha u sebelisa putty ea lebota.Sena se etsahala ha ho e-na le boitsebiso bo feteletseng holim'a metsi bo hlokang ho tlosoa.Sena se ka lebisa libakeng tse sa tsitsang le ho arola pente e sa lekaneng ha ho penta mabota.HPMC e ka eketsoa ho metsoako ea putty leboteng ho thibela ho benya ho etsahala.
HPMC e sebetsa joalo ka retarder ho putty leboteng, e fokotsa nako ea ho omisa ea motsoako.Sena se lumella putty nako e lekaneng ea ho lula holim'a metsi ntle le ho etsa lintho tse ngata.Ka HPMC, motsoako oa putty o ka sebelisoa ka sekhahla se le seng ntle le ho sebelisoa hape.
Ntle le moo, HPMC e eketsa viscosity ka kakaretso ea motsoako oa putty leboteng.Sena se bolela hore motsoako o tsitsitse ebile ha o na monyetla oa ho arohana kapa ho kopanya.Ka lebaka leo, motsoako oa putty oa lebota o bonolo ho sebetsa le ho ata habonolo holim'a metsi, ho fokotsa tlhokahalo ea ho senya.

Blisting ke bothata bo bong bo tloaelehileng bo hlahang nakong ea kaho ea putty ea lebota.Sena se etsahala ha putty e etsa lipokotho tse nyane tsa moea holim'a metsi ha e ntse e omella.Lipokotho tsena tsa moea li ka baka libaka tse sa tšoaneng 'me tsa senya ponahalo ea ho qetela ea lerako ha e pentiloe.HPMC e ka thusa ho thibela lipululo tsena ho theha.
HPMC e sebetsa joalo ka filimi ea mehleng ea lebota la putty.Ha putty e omella, e etsa filimi e tšesaane holim'a putty.Filimi ena e sebetsa e le tšitiso, e thibelang mongobo hore o kene ka hare ho lebota la putty le ho etsa lipokotho tsa moea.
Ho feta moo, HPMC e boetse e eketsa matla a bonding a putty ea lebota holimo.Sena se bolela hore putty e khomarela hantle holimo, e fokotsa ho thehoa ha mekotla ea moea kapa likheo pakeng tsa putty le bokaholimo.Ka HPMC, motsoako oa putty oa lebota o theha maqhama a matla le bokaholimo, a thibela ho hlaha ha makhopho.
