Wall putty chikamu chakakosha chemaitiro ekupenda. Musanganiswa wezvisungo, mafirita, pigment uye zvinowedzera zvinopa pamusoro pekupedzisira. Nekudaro, panguva yekuvakwa kwemadziro putty, mamwe matambudziko akajairika anogona kuoneka, senge deburring, furo, etc. Deburring ndiko kubviswa kwezvinhu zvakawandisa kubva pamusoro, nepo kuputika ndiko kuumbwa kwehomwe yemhepo madiki pamusoro. Zvose izvi nyaya zvinogona kukanganisa kuonekwa kwekupedzisira kwemasvingo akapendwa. Nekudaro, pane mhinduro kumatambudziko aya - shandisa HPMC mumadziro putty.
HPMC inomirira hydroxypropyl methylcellulose. Mushonga unoshandiswa zvakanyanya mumaindasitiri akasiyana siyana kusanganisira kuvaka. HPMC ndeye yakanakira yekuwedzera yemadziro putties sezvo ichivandudza kushanda, kubatana uye kusimba kwemusanganiswa. Imwe yemabhenefiti akakosha ekushandisa HPMC kugona kudzikisa deburing uye kuputika. Heino kupatsanurwa kwekuti HPMC inogona kubatsira sei kubvisa idzi nyaya:
Deburring
Deburring idambudziko rinowanzoitika kana uchiisa wall putty. Izvi zvinoitika kana pane zvinhu zvakawandisa pamusoro zvinoda kubviswa. Izvi zvinogona kutungamirira kune nzvimbo dzisina kuenzana uye kugovera pendi isina kuenzana paunenge uchipenda madziro. HPMC inogona kuwedzerwa kumadziro putty musanganiswa kudzivirira kupenya kubva kuitika.
HPMC inoita senge retarder mumadziro putty, ichidzikisa pasi nguva yekuomesa yemusanganiswa. Izvi zvinobvumira iyo putty nguva yakakwana yekugara pamusoro pepamusoro pasina yakawandisa zvinhu kugadzira. NeHPMC, musanganiswa weputty unogona kuiswa muchikamu chimwe chete pasina kudzokorora.
Uye zvakare, HPMC inowedzera iyo yakazara viscosity yemadziro putty musanganiswa. Izvi zvinoreva kuti musanganiswa wakanyanya kugadzikana uye kashoma kupatsanura kana agglomerate. Nekuda kweizvozvo, iyo wall putty musanganiswa iri nyore kushanda nayo uye inopararira nyore nyore pamusoro pepamusoro, ichideredza kudiwa kwekubvisa.
kutubukira
Blister nderimwe dambudziko rinowanzoitika panguva yekuvakwa kwemadziro putty. Izvi zvinoitika kana iyo putty ichigadzira mahomwe emhepo madiki pamusoro painooma. Aya mahomwe emhepo anogona kukonzera kusaenzana uye kukanganisa kutaridzika kwekupedzisira kwemadziro kana yapendwa. HPMC inogona kubatsira kudzivirira mabhuru aya kubva pakuumbwa.
HPMC inoita seyaimbova firimu mumadziro putty. Kana iyo putty inomesa, inoumba firimu yakaonda pamusoro peiyo putty. Iyi firimu inoita sechivharo, ichidzivirira mwando kupinda mukati memadziro putty uye kugadzira homwe dzemhepo.
Mukuwedzera, HPMC inowedzerawo simba rekubatanidza remadziro putty kumusoro. Izvi zvinoreva kuti putty inonamira zvirinani kumusoro, ichideredza kuumbwa kwehomwe dzemhepo kana mapeji pakati pe putty nepamusoro. NeHPMC, musanganiswa wewall putty unoumba chisungo chakasimba nechepamusoro, kudzivirira kuputika kubva kuitika.
mukupedzisa
Wall putty chikamu chakakosha chemaitiro ekupenda, uye zvakakosha kuve nechokwadi kuti ine kupera kwakatsetseka. Kuitika kwekudonhedza uye kuputika kunogona kukanganisa kutaridzika kwekupedzisira kwemadziro akapendwa. Nekudaro, kushandisa HPMC sechinhu chinowedzera kumadziro putty kunogona kubatsira kubvisa matambudziko aya. HPMC inoshanda seti retarder, ichiwedzera viscosity yemusanganiswa uye kudzivirira yakawandisa zvinhu kubva pakuumbwa pamusoro. Panguva imwecheteyo, inobatsira kugadzira chisungo chakasimba pakati pemadziro putty uye pamusoro, kudzivirira kuumbwa kwehomwe dzemhepo uye mabhubhu. Iko kushandiswa kweHPMC mumadziro putty kunovimbisa kuti kutaridzika kwekupedzisira kwemadziro akapendwa kwakatsetseka, kunyangwe uye kwakakwana.
