Chii chinonzi hpmc mumaindasitiri emakonzo?

HydroxyPropyl methylcellose (HPMC) ndeye polymer yakashandiswa zvakanyanya mumakonzo eindasitiri nekuda kwezvivakwa zvaro zvinoitika uye zvinoshanda. Senge isiri-ionic cellulose ether, hpmc iri synthesised kuburikidza nemakemikari kugadziridzwa kwemheremalose, chisikwa chinoitika polysaccharide. Uku kushandurwa kunopa HPMC ine hunhu hwakasiyana hunoita kuti zvinonyanya kukosha mukuumbwa kwemaindasitiri ematare emuindasitiri.

Chemical composition uye chimiro
HPMC inotorwa kubva ku cellulose, iyo inobatwa ne methyl chloride uye procylene oxide kuti inunge mapoka uye hydroxyprupropyl mapoka, zvichiteerana. Iyi yemakemikari yekugadziridzwa inoguma mune polymer iyo inonyungudika mumvura inotonhora uye inopisa, kusiyana nemheremalose cellalose. Dhigirii rekutsiva (DS) uye kutsiviwa kwemberi Iyo DS inoreva nhamba yehuwandu hwe hydroxyl mapoka pane iyo Anhydroglucese unit iyo yakavezwa mapoka ehuwandu hwemahara emapoka ezvikamu zvakadzama akasungirirwa pamamo eanhydroglucose unit.

Inoshanda zvivakwa mumaindasitiri emakonzo
Rheology shanduko: HPMC ndeyekubudirira kwakanyanya uye rheology modifier. Iyo inowedzera iyo visikopa yekubatanidza mafomu, iyo yakakosha yekuzadzisa iyo inodiwa kuyerera uye kuwanda zvivakwa. Izvi zvinovimbisa kuti kuunganidza kunogona kuiswa zvakanaka uye zvakafanana pasina kusekerera kana kumhanya, kuvandudza iwo maitiro ese ekupedzisa.

Film Ford: HPMC inobatsira kuumbwa kwefirimu rakabatana pane kuoma. Ichi chivakwa chakakosha mumatombo ekupa iyo inodzivirira uye yekuyera layer pamusoro substrates. Iyo firimu-inogadzira kugona kweHPMC inobatsira mune yekuchinja-shandura pigment uye yekuwedzera, inoverengera ruvara rwakaenderana uye chimiro.

Kudzokorora kwemvura: Mujasi-yakavakirwa mvura, HPMC inoshanda seyekuchengetwa kwakanaka kwemvura. Zvinobatsira kudzivirira kuomarara kwekucheka kwekucheka, kubvumira kwenguva yakareba yekushanda uye kushamisika kuri nani kune substrate. Izvi zvinonyanya kubatsira mukushandisa mairi mayunivhesiti mamiriro ezvinhu anogona kukonzera nekukurumidza kwemvura kubuda kwemvura.

STabilization: HPMC inoita kunge stabilizer yemapipi uye zvimwe zvakaparadzaniswa zvimedu mubatanidzwa. Iyo inodzivirira shedimentation uye akajaira, kuchengetedza yunifomu yekupararira mumamiriro ekunyorera. Iyi stebilization iri kutsoropodza kuwana mukana wekuwirirana uye kuita.

ADHesion uye kusungwa: Iyo Polymeric chimiro cheHPMC inowedzera iyo inonamatira zvivakwa zvejasi. Iyo inovandudza chisungo pakati pekuvhara uye substrate, iyo yakakosha kuti isimbe uye kuramba kuzvimanikidza kwemuchina. Izvi zvinonyanya kukosha mumaindasitiri ekushandisa maindasitiri anowanikwa nemamiriro ezvinhu akaomesesa mamiriro.

Zvikumbiro mumaindasitiri
Kuzvidzivirira kwezvivakwa: Muzviratidzo zvekuvaka uye kuungana, HPMC inoshandiswa kugadzirisa zvivakwa zvekushandisa uye chitarisiko chekupedzisira. Kugona kwayo kudzora viscosity uye kusimudzira mafirimu ekuumbwa kunoita kuti ive yakakodzera kune yemukati uye yekunze pendi.

Zvipfuyo zvinodzivirira: Mukudzivirira uye zvinodzivirira uye zvinokosha zvejasi, HPMC inobatsira mukuzadzisa huku hwaunoda uye kufanana. Izvo zvinopawo kusimba kwekubatira, kuchengetedza simbi uye kongiri nzvimbo kubva kune zvakasvibiswa zvemunharaunda.

Zvekutakura zvemotokari: Mune zvigadzirwa zvemotokari, HPMC AIDS mukuwana zvakapetwa zvinopedza uye yunifomu yekugoverwa. Zvivakwa zvayo-zvinogadzirisa zvinhu zvine chokwadi chekuti machira anogona kuiswa zvakanaka pazvinhu zvakaoma zvemotokari.

Marine Coatings: HPMC inoshandiswa mumarinda emarungu kupa zvipinganidzo kumvura nemunyu. Yayo firimu-inogadzira zvinhu uye zvinonamira zvivakwa zvinobatsira mukudzivirira ngarava uye zvivakwa zveganda kubva kuPorrosion uye biofouling.

Maindasitiri ekugadzirisa maindasitiri: zvekugadzirisa uye kugadzira machira mumaindasitiri mumaindasitiri, HPMC inopa iyo inodiwa viscosity control uye yefirimu kutendeka kwaida kukurumidza uye inoshanda application.

Zvakanakira kushandisa HPMC mune maindasitiri emakonzo
Kuedza: HPMC inoenderana nehuwandu hwakawanda hwekuumbwa kwezvinhu, zvichiita kuti ive chinhu chose chikamu mumhando dzakasiyana siyana dzejasi. Inogona kushandiswa mune ese maviri emvura uye solvent-yakavakirwa masisitimu, kunyangwe iyo yekutanga application iri mumvura-yakavakirwa mvura.

Zvakanakira Zvemamiriro ekunze: SePoluble-Solble Polymer, HPMC inotsigira kuvandudzwa kwemakiromita ane hushamwari. Iyo inobatsira mukuderedza kuvimba kweiyo kusiririsa organic makomputa (VOCS), zvinobatsira kuti zviwedzere mashandisirwo uye nzvimbo yakashanda yakashanda.

Kuregedza kweshandishoi: HPMC iri nyore kubata uye kubatanidza muhukadzi mafambiro. Inopaza nyore mumvura, kugadzira mhinduro dzakajeka dzinogona kuvhenganiswa nyore nyore nezvimwe zvinosanganiswa.

Mutengo-kushanda: Paunenge uchipa akawanda anoshanda mabhenefiti, HPMC inodhura-inoshanda. Iyo inokwidziridza kuita kwejasi risina kuwedzera zvakanyanya mari yekuumbwa.

Zvinonetsa uye kufunga
Pasinei nezvakanakira zvakawanda zvakawanda, kune mamwe matambudziko anoenderana nekushandiswa kweHPMC mune maindasitiri ekutora:

Tembiricha yekudziya: HPMC mhinduro dzinogona kuve nehanya nekuchinja kwekushisa, izvo zvinogona kukanganisa viscosity uye kugadzikana kwekuchengetwa panguva yekuchengetedza uye application. Kuumbwa nokungwarira uye kuongororwa kunodiwa kuti uve nechokwadi chekuita kuita.

Nyaya dzinoenderana: Kunyangwe kazhinji zvichienderana nehuremu hwakasiyana Izvi zvinoda kunyatsoenderana kuongororwa panguva yekuumbwa kwekuumbwa.

Biodegradability: Ipo HPMC inotorwa kubva kune yakasikwa cellulose, iyo yemakemikari yekugadziridza inogona kukanganisa biodegradabiladabiladabiladabiladabiladabiladabiladabiladabiladabiladabiladabiladabiladabiladabiladabiladabilad Iko kune rondedzero inoenderera mberi yekuwedzera iyo nhoroondo yeHPMC nekukudziridza yakawanda biodeldalable viants.

HydroxyPropyl methylcellose (HPMC) chinhu chakakosha mune rezvipfuyo zvematanda, zvinopa musanganiswa weReology kuchinjika, kuumbwa kwefirimu, kudzikisira kwemvura, uye kugadzikana, uye kudedera. Kuedza kwazvinoita, zvakanakira zvepakatiridzwa, kusunungurwa kwekushandisa, uye zvinodhura-zvinoita sarudzo inosarudza muzvishandiso zvakasiyana siyana, kubva kuzvipatara uye zvekugadzira uye zvemotokari kuti zvive zvekudzivirira uye zvirongwa zvekudzivirira. Nekudaro, mafomu anofambisa anofanirwa kufamba nematambudziko akadai sekupisa kwekushisa uye nyaya dzinoenderana kuti dziwedzere kubatsirwa zvakanaka zveHPMC. Sezvo kudikanwa kwekuita kwakanyanya uye nemamiriro ezvinhu ane hushamwari kwakakura, HPMC icharamba ichitamba basa rakakosha mukufambira mberi kubata matekinoroji.
