300 White kana grey yevhu simende 42.5
220 silica poda (160-200 mesh)
450 inorema calcium poda (0.045mm)
6-10 Redispersible polymer poda (RDP) ET3080
4.5-5 HPMC MP45000 kana HEMC ME45000
3 white wood fiber
1 polypropylene faibha (ukobvu 3 mm)
Wall putty inosanganisira yemukati madziro putty uye yekunze madziro putty. Basa rayo guru nderokugadzirisa kusaenzana uye kuita kuti rusvingo ruve nyore.
1.1 Adhesive
Iwo anosungira mumadziro putty formula simende, yakakwira-viscosity polymer hupfu, uye slaked lime. Simende inoshandiswa zvakanyanya pakuvaka. Iyo ine mukurumbira nekuda kwekunamatira kwayo kwakanaka, kuomarara kwepamusoro uye kudhura kwekuita. Asi kusimba kwekusimba uye kuramba kwekuputika kwakashata. Powder Powder ipuromeri inodhindwa zvakare. Inogona kuita basa rekubatanidza mumadziro putty formula.
1.2 Kuzadza
Mafirita ari mumadziro putty formula anoreva heavy calcium carbonate, Shuangfei poda, grey calcium poda, uye talc poda. Kunaka kwekukuya calcium carbonate kunosvika mazana maviri mesh. Usashandise mafirita akanyanya granular mumadziro ako putty formula. Izvi zvinoguma nekusaenzana flatness. Fineness chinhu chakakosha mumadziro putty formulations. Bentonite ivhu dzimwe nguva inowedzerwa kuti iwedzere kubata.
1.3 Midziyo yekubatsira
Zvinowedzerwa mumadziro putty formulas zvinosanganisira cellulose ethers uye VAE redispersible latex poda. Rudzi urwu rwekuwedzera runoita basa rekukora uye kuchengetedza mvura. Iwo makuru cellulose ethers iHPMC, MHEC, uye CMC. Huwandu hwe cellulose ether hunoshandiswa hwakakosha pakuumbwa kunoshanda.
Hydroxypropylmethylcellulose
Mune HPMC chimiro, imwe kemikari inonzi hydroxypropionyl. Iyo yakakwira iyo hydroxypropoxy boka zvirimo, zviri nani kuchengetedza mvura. Imwe kemikari inonzi methoxy. Iyo tembiricha yegel inobva pairi. Munzvimbo dzinopisa, vashandi vanobhadhara zvakanyanya kune chiratidzo ichi. Nekuti kana ambient tembiricha yakapfuura tembiricha yegel yeHPMC, cellulose inodonha kubva mumvura uye yorasikirwa nekuchengetedza kwayo mvura. Kune MHEC, tembiricha yegel yakakwira kupfuura yeHPMC. Naizvozvo, MHEC ine nani kuchengetedza mvura.
HPMC haina kuita makemikari maitiro. Iine mvura yakanaka kuchengetedza, ukobvu uye kushanda.
1. Consistency: Cellulose ether inogona kukora uye kuchengeta yunifomu yemushonga ichikwira nekudzika. Inopa wall putty yakanaka sag resistance.
2. Kuchengetwa kwemvura: Deredza kuoma kwekuoma kweputty powder. Uye inobatsira kumakemikari anoita pakati pegrey calcium nemvura.
3. Kushanda kwakanaka: cellulose ether ine lubricating function. Izvi zvinogona kupa madziro putty zvakanaka workability.
Redispersible polymer poda inoreva VAE RDP. Chiyero chayo chakaderera. Vamwe vashandi vanogona kusawedzera kumadziro putty formula kuchengetedza mari. RDP inogona kugadzira madziro putty kureruka, kusapinda mvura uye kuchinjika. Kuwedzeredzwa kwepolymer inodzokororwa poda inomhanyisa application uye inovandudza kutsetseka.

Dzimwe nguva, mapeji emadziro emadziro ane fiber, senge polypropylene fibers kana huni fibers. PP fiber kongiri inzira inoshanda yekudzivirira kutsemuka.
polypropylene faibha kongiri
Mazano: 1. Kunyange zvazvo cellulose ether chinhu chinokosha muputty powder formula. Nekudaro, iyo dosage ye cellulose ether inofanirawo kunyatsodzorwa. Izvi zvinodaro nekuti cellulose ethers, senge HPMC, inogona kuiswa emulsified. Kana ikashandiswa zvakawandisa, cellulose ethers inogona kumisa uye kupinza mweya. Panguva ino, putty inotora mvura yakawanda nemhepo. Mushure mokunge mvura ichiputika, putty layer inosiya nzvimbo huru. Izvi zvinozopedzisira zvakonzera kuderera kwesimba.
2. Rubber poda chete inowedzerwa kumadziro putty formula, uye hapana cellulose inowedzerwa, iyo ichaita kuti putty ave upfu.
2. Mhando dzemadziro putty
HPMC wall putty inoshandiswa kumadziro putty inosanganisira yemukati madziro putty uye yekunze madziro putty. Kunze kwemadziro putty kuchakanganiswa nemhepo, jecha, uye kupisa kwekunze. Naizvozvo, ine mamwe mapolymers uye ane simba repamusoro. Asi index yayo yezvakatipoteredza yakaderera. Nekudaro, iyo yakazara zviratidzo zvemukati madziro putty zviri nani. Interior wall putty formula haina zvinhu zvinokuvadza.
Wall putty formulas inonyanya kusanganisira gypsum-based wall putty uye simenti-yakavakirwa madziro putty. Aya mafomula anosanganiswa nyore nemabhesi. Iko kune wall putty recipe sezvinotevera:
2.1 White simende-yakavakirwa madziro putty formula
White simende-yakavakirwa madziro putty inogona kushandiswa mukati uye kunze kwemadziro. Zvose grey uye kongiri madziro anogona kuishandisa. Rudzi urwu rweputty runoshandisa simenti chena sechinhu chikuru. Fillers uye additives zvinobva zvawedzerwa. Mushure mekuoma, hapana kunhuhwirira kusingafadzi kuchagadzirwa. Cement-based formula inopa simba rakakura uye kuoma.
2.2 Acrylic wall putty formula
Acrylic putty ndeye acrylic adhesive yakagadzirwa kubva kune yakakosha zvinhu. Iine peanut butter-like consistency. Inogona kushandiswa kuzadza makatsemuka uye maburi maburi mumadziro
Ndeupi musiyano uripo pakati pesimende-based wall putty uye acrylic wall putty?
Acrylic putty yakakodzera kumadziro emukati, asi inodhura kupfuura simende-based putty. Kuramba kwayo alkali uye kuchena zvakare zviri nani pane simende-based putty. Uyezve, inoomesa nekukurumidza kupfuura simende chena, saka basa rinoda kuitwa nekukurumidza.
2.3 Flexible wall putty formula
Flexible putty ine yemhando yepamusoro simende, mafirita, synthetic polymers uye zvinowedzera. Uye kubuda kwezuva hakuzokanganisa kuvakwa kweputty. Flexible putty ine yakakwirira yekubatanidza simba, yakatsetseka uye yakatsetseka pamusoro, uye inodzivirira mvura uye hunyoro-huchapupu.
Muchidimbu
Pakusarudza iyo chaiyo putty formula, kazhinji hazvigoneke kutaura nezve yekutanga fomula. Formula yacho inofanirwa kusanganiswa nenharaunda, senge hunhu hwedunhu, hunhu hwezvinhu zvakasvibirira… Iyo yakanyanya kunaka putty formula ndeyekuisa putty zvinoenderana nemamiriro enzvimbo. Shandura iyo putty formula kuti uwane iyo scraping athari.
