Abstract:Mhedzisiro yezvinhu zvakasiyana zve hydroxyprupyl methylcellose ether pane zvivakwa zvekunyanyisa kuomarara-yakasanganiswa moterret. Mhedzisiro yacho yakaratidza kuti: Kuwedzera kwezvinhu zvemanyorero eCellulose ether, kusvererwa uye density yakaderera, uye nguva yekugara yakadzikira. Kuwedzerwa, simba 7d uye 28D rakadzvinyirira, asi kuita kwese kwekuomesesa-kwakasanganiswa-kusanganisa.

Muna 2007, masisitiri matanhatu uye emakomisheni enyika akaburitsa "ziviso pakurambidza pa-saiti kusanganisa kwemutya mune mamwe maguta mukati menguva yakatarwa". Parizvino, maguta zana nemakumi matatu nenomwe mhiri kwenyika akaenderera mberi nebasa re "duriri riripo, iro rakauya nekusimudzira kusiri kusimba mukuvandudzwa kwemotokari yakaoma. mukana. Nekuvandudzwa kwakasimba kwekuomeswa-kwakasanganiswa mumisika yemumba uye yekune dzimwe nyika, asi madhiri ekutengesa anowedzera nemaune nemaune kune zvigadzirwa zvavo, kutsausa iyo yakaoma-yakasanganiswa muindasitiri. hutano uye kurongeka kukura. Parizvino, kunge kongiri yekubvumirana, yakaoma-yakasanganiswa moterr admixture inonyanya kushandiswa musanganiswa, uye vashoma vanoshandiswa ndega. Kunyanya, kune akawanda emhando dzemhando dzekurwadziwa mune mamwe mongwe dzinosanganiswa dzakaoma-dzakaomeswa, asi pane imwe dhayeti yakaoma yekuita kuti ishandiswe. Muzvakajairika-zvakajairika-yakasanganiswa dhaka, cellulose ether inoita basa rekuchengeta mvura, kurerutsa, uye kuvandudzwa kwekuita kwekuvaka. Kurovedzera kwemvura Kuroverwa kunovimbisa kuti iyo yakaoma-yakavhenganiswa mongwe haizo kukonzera sanding, poda nekudzikisira uye kuderedzwa kwesimba nekuda kwekushomeka kwemvura uye isina kukwana simment hydration; Iko kukonzeresa mhedzisiro inosimbisa kwazvo simba rekusimbisa kweiyo yakanyorova dhiri. Iri pepa rinoitisa fundo yekudzidza pane yekushandiswa kwemhereman mherether mune yakajairika yakaoma yakaoma-isina kuoma, iyo ine kukosha kwekutungamira kwekushandisa mafambiro anonzwisisika mune yakajairika yakaoma yakaoma-yakavhenganiswa.
1. Zvishandiso uye nzira dzinoshandiswa muedzo
1.1 zvishandiso zvebvunzo
Iyo simende yaive P. 042.5 simende, iyo Ash yekirasi II ATHE SEAYUANCE, iyo Cellulose Atter
1.2 bvunzo nzira
Sampule kugadzirira uye kuongororwa kwekuita kwakaitwa maererano neJCJ / T 70-2009 Basic Palfor Performance Test nzira yekuvaka moter.
2. Chirongwa cheyedzo
2.1 formula yebvunzo
Muedzo iyi, huwandu hwezvinhu zvega zvega zvegumi zvemukati zvemari dzakaoma-dzakasanganiswa.
2.2 chirongwa chakananga
Uchishandisa iyi formula, huwandu hwe hydroxypropyl methylcellose ether yakawedzerwa kune imwe toni yakaomeswa-madhiri. Kuchengeta, kusanzwisisika, kusimba kwekusimbisa, uye kusimbisa nguva yakasanganiswa-kusanganisa kusasanganiswa kwekurongedza kwerudyi.
3. Mhedzisiro uye kuongororwa
3.1 Mhedzisiro
Mhedzisiro yemadhorobha akasiyana e hydroxyprupyl methyelcellose ether kuchengetwa kwemvura, kusanzwisisika, kusimba, nekumisikidza nguva, uye simba rekunyanyisa rakaoma-rakavhurika.
3.2 kuongororwa kwemhedzisiro
Zvinogona kuoneka kubva pamhedzisiro yemadhorobha akasiyana e hydroxypressl metdlcellose ether kuchengetwa kwemvura, kusimba, kurongedza nguva, uye simba rekumanikidza rekupenya rakaoma-rakasanganiswa. Nekuwedzera kwemasero eCellensi yeCellensi yezvinyorwa, iyo mvura yekuchengetera mvura iri kuwedzera zvakare kuwedzera, kubva pa 86.2% kana hydroxypropyl Cellyl Cellyl Iyo yekuchengetwa kwemvura inosvika 96.3%, iyo inoratidza kuti iyo mvura yekuchengeta kwemvura yeProyl methyl cellelose ether yakanaka kwazvo; Kuenderana zvishoma nezvishoma kunoderera pasi pemvura yekuchengetwa kwemvura yeProyl methyl cellerl Cellyl Cellyl Cellyl Cellyl Cellyl Cellyl Iko kuoneka kunooneka kunoratidza kutsika-tsika, zvichiratidza kuti mvura yekuchengetwa kwemvura yeProyl methyl cellerlose ether inowedzera huwandu hwevhu remarara uye rinoderedza dentity; Iyo nguva yekuedza zvishoma nezvishoma inowedzera nekuwedzera kweiyo hydroxypressl methelose lefherproproproproproproproproproproprollose ether yekudzora nguva yekuvhiringidza nguva yekuvhenekera. Simba rekumanikidza re7D uye 28d rakaderera (iyo yakakura dosage, iyo iri pachena kuderedzwa). Izvi zvine chekuita nekuwedzera kwehuwandu hwevhu uye kuderera kwekusarongeka kunooneka. Kuwedzerwa kwehydroxypropyl methyl celler cellulese ether kunogona kuumba iyo yakavharwa cavity mukati meiyo yakaoma motokari mukati mekugadzika uye kuomesa musoro. Micropopores inovandudza kusimba kwemutema.
4. Kuchengetera kwekushandisa kwemheremalose ether mune yakajairika yakaoma-yakasanganiswa dhiri
1) kusarudzwa kwe cellulose ether zvigadzirwa. Kazhinji, iyo yakakura view ye cellulose ether, iri nani yekuchengeta kwemvura, asi yakakwira iyo visikoka, iyo yakadzika solubility, inokuvadza kusimba uye yekuvaka yemota; Iyo yakajeka ye cellulose ether yakadzika yakaderera mune yakaoma-yakasanganiswa dhiri. Zvinonzi izvo zvakanakisa ndezvekuti, zviri nyore kunyungudika. Pasi pemvura imwe chete, iyo yakanakisa iyo yakajeka, iri nani kuchengetwa kwemvura.
2) kusarudzwa kwe cellulose ether dosage. Kubva pamhedzisiro yebvunzo uye kuongororwa kwemhedzisiro yezvinyorwa zveCellulose kuitwa kweCellering Erstering Darman Iyo Dosage yeHydroxyPropyl methyl celler cellown cellyl fritary yakaoma-madhiri inowanzoitika Tsaona yemhando; Iyo Dosage yeHydroxyPropyl methyl celler cellulose ether mune inokosha yekupaza-inodzivirira kupururudza motsi inenge 3 kg / t.
3) Kushandiswa kwe cellulose ether mune yakajairika yakaoma-yakasanganiswa dhiri. Mukuita kwekugadzirira zvakajairika yakaoma-yakavhenganiswa, huwandu hwakakodzera hwekurwiswa hunogona kuwedzerwa, nekukasira nekuwedzera kwekuchengetwa kwemvura uye kuti ingagadzirire mishonga yekubatanidza ether, kuderedza mari yekugadzira, uye chengetedza zviwanikwa; Kana ikashandiswa wega kune cellulose ether, simba rekubatanidza harigone kuzadzisa zvinodiwa, uye huwandu hwakakodzera hwenzvimbo dzinotariswa latex hunogona kuwedzerwa; Nekuda kweiyo yakaderera huwandu hwehudhudhudhudhudhudhudhudhi, kukanganisa kuyerwa kwakakura kana kuchishandiswa wega. Kunaka kwezvigadzirwa zvakaoma-motsi.
5. Mhedziso uye mazano
1. Simba rekumanikidza re 28d rakaderera, asi basa rakawanda rekusanganisa rakaoma-rakavandudzwa kana zviri mukati mehydroxyprupyl mether.
2) Mukutonga kwekugadzirira zvakajairika-yakavhenganiswa motokari, cellulose ether newisikopo neyekuona kwakakodzera uye musanganiswa unofanirwa kusarudzwa, uye dosage yaro inofanirwa kutsanangurwa zvakanyanyisa kubudikidza nekuedzwa. Nekuda kweiyo yakaderera huwandu hwehudhudhudhudhudhudhudhudhi, kukanganisa kuyerwa kwakakura kana kuchishandiswa wega. Zvinokurudzirwa kusanganisa iyo neyekutakura kutanga, uye wobva wawedzera huwandu hwekuwedzera kuti uve nechokwadi chehunhu hwezvigadzirwa zvakaoma-motsi.
3) yakaoma-yakavhenganiswa motsi indasitiri inobuda muChina. Mukutonga kwekushandisa mongororo yerudzi, hatifanire kutevedzera mapofu, asi tarisazve kumhando uye kuderedza mari yekugadzira, kukurudzira marara emaindasitiri, uye kuzadzisa kudzikiswa kwesimba uye kwekuparadza simba.
