Hydroxyprupyl methylcellose (HPMC)Iyo Polymer Polymer inotorwa kubva kuCellulose, uye inowana kushandiswa kwakapararira mune dzakasiyana siyana dzekutengesa uye dzekutengesa zvikumbiro nekuda kwezvivakwa zvaro zvinoitika. Imwe yematanho ayo akakosha ari kuita seyakagadzirwa mune zvekuvaka zvinhu, kunyanya mune zvekupfeka. Putty, chinhu chinowanzoshandiswa mune yekuvaka indasitiri yekuzadza, zvinyoro-nyoro, kana zvinokatyamadza, zvinobatsira kwazvo nekubatanidzwa kweHPMC.
1. Kunzwisisa kuumbwa kwekutenderera
Putty chinhu chakafanana nechinhu chakafanana chinowanzoumbwa nechisikwa, chinogadzirwa zvinhu, uye zvinowedzera. Iyo Binder inowanzo kuve yezvinhu zvinonamatira senge simende, gypsum, kana resin, nepo mafirita anogona kusanganisira zvinhu zvakadai se talc, kaolin, kana zvimwewo zvakanaka. Vanowedzera kunge mapurasitiki, thickeners, uye lubriceants, uye lubrice vanoratidzwa kuti vagadzirise zvinhu zvekutyisa, sekushanda kwayo, nguva yekuoma, uye kusimba simba.
Lubricants like Kigall®hpmc inowedzerwa kuti uvandudze maitiro ekubata ePutty, zvichiita kuti zvive nyore kushandisa uye zvakatsiga pamusoro pemamiriro ezvinhu. Pasina maLubriants, putty inogona kuve yakakora kwazvo, yakaoma, kana yakaoma kupararira. Basa reHPMC sevanogara zvakanyanya mukuvandudza zvivakwa zvakatsanangurwa uye kuona chimiro chakanyatsojeka uye chinoshanda chekureruka kwekushandisa.
2. HPMC: kupfupi kuongorora
HydroxyPropyl methylcellose (HPMC) is cellulose derivative, nemakemikari akagadziridzwa kuti agadzirise iyo solubility yemvura inotonhora. Iyo polymer ine musangano weCellulose neHydroxypruppropyl uye methyl mapoka akasungirirwa, ayo anoshandura zvivakwa zvayo. Iko kushandurwa kunoguma nekukanganiswa uko kunonyanyoka mumvura asi kusakwana mune yakawanda organic sol sol.
HPMC chinhu chakakosha mune zvakawanda zvekuumbwa, kusanganisira pendi, zvinoshatisa, zvizarisi, mishonga, mishonga, uye zvigadzirwa zvekuvaka. Zvivakwa zvaro zvepamusoro zvinosanganisira kuchengetwa kwemvura, kurerutsa, uye kugadzira gl-senge kusawirirana. Pamusoro pezvo, HPMC isiri-ionic, zvinoreva kuti haina kupindirana nemamwe madzishe akaiswa muumbi, achibvumira kushanda sechigadzirwa uye lubricant pasina kukanganisa mari yemakemikari echigadzirwa.
3. Mechanism yeLubrication muPutty
Kana ikabatanidzwa muPutty, HPMC inoshanda munzira dzinoverengeka dzekuvandudza basa rekushanda kwezvinhu:
Kuderedzwa kwekupokana: Iyo polymer mamebluecules muHPMC inobata pamwe nezvimwe zvinoshandiswa mune iyo putty kuti iite firimu pamusoro peiyo firimu zvimedu zvechishanu. Iyi firimu inobatsira kuderedza kupokana pakati pezvikamu, zvichiita kuti zvinhu zvive nyore kupararira uye kushandisa. Iyo yakasvibiswa inosimbisa inovimbisa kuti iyo putty haina dhonza pamusoro, izvo zvaizoita kuti zviome zvakaoma kuwana yunifomu kupera.
Yakavandudzwa kuyerera: HPMC yekuchengetwa kwemvura inochengetedza zvakare inopa zvakare kuvandudza kuyerera muPutty. Izvo zvinobvumira iyo pasita kuti irambe yakanyorova uye inoshanda kwenguva yakareba, iyo inonyanya kukosha pakuvaka yekuvaka uko nzvimbo huru dzinoda kuvharwa. Iyo lubricant mhedzisiro inobatsira iyo putty kuyerera zviri nyore pamusoro pekutsarura, kuderedza kuedza kunodiwa kuti ishandiswe.
Kuwedzera Kushanda: Chimwe chezvakakosha zvakanakira Hpmc mune putty mafomu ndeyekuwedzera kwekushanda. Nekuderedza iyo visikoka yeiyo putty, HPMC inoita kuti ive inokwanisa kurwadza, kunyangwe kana ikashandiswa muzvikamu zvakakora. Izvi zvinonyanya kukosha kana uchishanda nemadziro ekuisa, mainini makomputa, kana kuti mavara ekupedza ipo ingafungidzirwa uye kushoma ndiko kuzadzisa nyanzvi yemhando.
Kudzivirira kwekutambisa uye kusunganidzwa: mune akawanda putty mafomu, izvo zvinhu zvechisimba zvinowanzo zora kana kuunganidzira pamwe chete, kunyanya kana wakabatanidzwa kana kuchengetwa kwenguva yakareba. HPMC's Lubricing mhedzisiro inobatsira kudzivirira izvi, kuchengeta zvigadzirwa zve-firita zvakaparadzirwa mumusanganiswa murefu. Uyu kufanana unovimbisa kuti iyo putty inochengetedza zvivakwa zvayo zvaunoda muhupenyu hwayo hwesherufu.
4. Kubatsira HPMC seyekucherekedza muPutty
Kubatanidzwa kweHPMC muPutty kunopa akati wandei zvakanakira:
Yakavharirwa Kupararira: Chimwe chezvikonzero zvakakosha HPMC inofarirwa muPutty mafomu maitiro ayo kugona kwayo kuvandudza kupararira. NaHPMC, iyo putty inogona kuparadzirwa zvakanyanya uye zvakanaka, kuderedza nguva uye kushanda nesimba kunodiwa pakushandisa. Izvi zvinonyanya kubatsira mumabasa makuru-ekuvaka mapurojekiti aripo application application yakakosha.
Kuenderana kwekupedza: Iyo lubricant mhedzisiro yeHPMC inovimbisa kuti iyo putty haina kuoma nekukurumidza kana kuti yakanyanya kukakavara panguva yekushandisa. Izvi zvinoguma nekupedzisa kupedzisa, nekusakwana kushoma senge madhiri, makomba, kana nzvimbo dzisina kufanana. Kune nyanzvi mune yekuvaka indasitiri, uku kuenderana kwakakosha kuendesa basa remhando yepamusoro.
Yakaderedzwa ganda kana kupaza: mune akawanda putty mafomu, apo chigadzirwa chinofamba, chinogona kuumba ganda kana kupwanya, kunyanya kana uine yakakwira firiki. HPMC yemvura yemvura-yekuchengetwa inobatsira kuchengetedza zvinyoro-nyoro mune mukana wenguva yakareba, kuderedza mikana yekusagadzikana, ganda, kana kupaza. Izvi zvinovandudza kusimba uye hupenyu hurefu hweiyo yakaiswa putty.
Kuwedzera Reserfu Hupenyu: HpMc yemvura yekuchengetedza uye basa rayo seStabilizer inogona kupa hupenyu hwakatambanudzwa hwesherufu yezvigadzirwa zvechigadzirwa. Sezvo iyo inobatsira kudzivirira iyo zvinyorwa kubva pakuomesa kunze kana kuve wakanyanya kukwirira kwenguva yakareba, izvo zvakakosha muindasitiri yekuvaka uko huwandu hwehuwandu hwevhu hunowanzochengetwa nguva zhinji.
Kuchengetedza Zvemamiriro ekunze: Sezvo cellulose Detivative, Kimicell®hpmc chinhu chebhokisi uye chisiri chepfu. Kushandiswa kwayo seyakagadziriswa muPutty kunoita kuti chigadzirwa chiwedzerwe neushamwari tichienzanisa neyakagadzirwa maLubricants, ayo anogona kusanganisa nharaunda kana hutano njodzi. Izvi zvinonyanya kukosha mune yanhasi zvakatipoteredza indasitiri yekuvaka yekuvaka, uko kudiwa kwezvinhu zvakanaka zvinowedzera.
5. Zvikumbiro mukuvaka uye kupfuura
HPMC inoshandiswa mune yakasarudzika huwandu hwekutenderera, kubva kumadziro putties uye macompany mishonga yemiwiza inonamira uye kuumbwa. Kuita kwayo kunoshamisa kunobvumidza kuti kuisirwa muzvinhu zvese zvechinyakare zvetsiva-zvakavakirwa mari uye newer polymer-yakagadziriswa mafomu. Nekuwedzera kuyerera uye kupararira kweiyo putty, HPMC inovimbisa kuti zvigadzirwa izvi zvinosangana nezvinodiwa maitiro ekuita kweindasitiri yekuvaka.
Pamusoro pekushandiswa kwayo muPutties, HPMC inowanzo kuwanikwa mumapende uye majasi, kwaunobatsira kudzora zvivakwa uye kugadzirisa zvinhu zvakazara zvechigadzirwa. Mhedzisiro yayo inosimbisa inovimbisa michero yakatsiga, yunifomu iyo inogona kuiswa nyore nyore.
Hpcinoita basa rakakosha mukuvandudza mashandiro ezvimiro zvekutakura nekuita kunge lubricant. Kugona kwayo kuderedza kupokana, kusimudzira kuyerera, kuvandudza basa rekushanda, uye kudzivirira kuunganidza uye kusunganidzwa kunoita kuti ive inowedzera chinowedzera pane zvigadzirwa zvekuvaka. Zvakanakira HPMC inowedzera kusunungurwa kwekushandisa kuti isanganise kuwedzera kusimba, kusawirirana, uye kuchengeteka kwezvakatipoteredza. Sezvo indasitiri yekuvaka ichiramba ichishanda zvakanaka uye inotsigira, basa reHPMC sechipo muPutty uye zvimwe zvinhu zvekuvakira zvicharamba zvichikosha mukuzadzisa mibairo yepamusoro.
