Poda yeKaolin Yakagadziriswa Pamusoro Yeindasitiri yePurasitiki Inovandudza Simba reMichina uye Kuramba Kupisa
Tsananguro pfupi:
Kuenderera mberi kweindasitiri yepurasitiki kunoda michina yekuzadza zvicherwa yepamusoro inogona kugadzirisa mashandiro ezvigadzirwa panguva imwe chete, kuderedza mari yekugadzira, uye kuwedzera miganhu yekushandisa. Pakati peizvi, upfu hwekaolin hwakagadziriswa pamusoro hwakabuda sechinhu chinowedzera simba, zvichichinja kugadzirwa kwezvigadzirwa zvepurasitiki zvakasiyana-siyana zvinosanganisira polypropylene (PP) injection-molded components, polyethylene (PE) films, uye polyvinyl chloride (PVC) profiles. Kusiyana nechinhu chisina kugadziriswa, icho chinowanzo ratidza kusawirirana zvakanaka nemapurasitiki, upfu hwekaolin hwakagadziriswa pamusoro hunoshandisa silane kana titanate coupling agents kuti hugadzire zvisungo zvakasimba zvemakemikari nemaketani epolymer. Kudyidzana uku kwemazinga emamorekuru kunowedzera simba remuchina, kugadzikana kwekupisa, uye kufanana kwekupararira mukati mematrikisi epurasitiki, zvichiita kuti ive chinhu chakakosha mukugadzirwa kwemapurasitiki emazuva ano.
Kuwedzera Simba reMichina
Kusimba kwemuchina kunomiririra senzira isingachinjiki yezvigadzirwa zvepurasitiki, kunyanya izvo zvinoshandiswa muzvikamu zvinoda simba zvakaita seinjiniya yemotokari, zvivakwa zvekuvaka, uye zvinogara kwenguva refu zvevatengi. Upfu hwekaolin hwakagadziriswa pamusoro, hunowanzo verengerwa pakati pe1000 ne2000 mesh, hunoshanda semushonga wekusimbisa nekugadzira network yakaoma ye mineral-polymer interfacial bonds. Network iyi inobatsira kugoverwa kwakaenzana kwesimba remuchina mupurasitiki, kudzivirira kuwanda kwesimba kunogona kukonzera kukundikana.
Muindasitiri yemotokari, uko kuderedza huremu uye kusimba kwechimiro kuri kukuru, kuwedzerwa kwe10%-20% yeupfu hwekaolin hwakagadziriswa pamusoro (nehuremu) kuzvinhu zvemukati zvePP zvemotokari—zvakadai semabhokisi edashboard nemagonhi—kwaratidza kuvandudzika kunoshamisa. Kuedzwa kwakasimba kwakaitwa nemutengesi wezvikamu zvemotokari wekuGermany kwakaratidza kuwedzera kwe25%-35% musimba rekudhonza, zvichikwidza kukosha kubva pa30 MPa kusvika pa37-40 MPa. Panguva imwe chete, flexural modulus yakaona kuwedzerwa kwe40%-50%, kubva pa1500 MPa kusvika pa2100-2250 MPa. Kubudirira uku kunobvumira vagadziri kuderedza kushandiswa kweresin kusvika pa15%, vachiwana kuchengetedza mari yakawanda pasina kukanganisa kunaka kwechigadzirwa.
Kune mafirimu ekurima ePE, kugadziriswa kweupfu hwekaolin pamusoro kunoita kuti pave nehunhu hwakanaka hwekupararira, zvichidzivirira kuungana kwezvikamu zvinogona kukonzera kusasimba kwechimiro. Mafirimu ane 8%-12% yeupfu uhwu hwakagadziriswa akaratidza kuwedzera kwe30% mukudzivirira kukuvadzwa, zvichiwedzera kubva pa8 kJ/m² kusvika pa10.4 kJ/m². Kugara kwenguva refu uku kunobvumira mafirimu kuti agone kutsungirira kumhanya kwemhepo kusvika ku18 m/s pasina kubvaruka, zvichipa dziviriro yakavimbika kune mamwe mashandisirwo emaindasitiri kunze kwekurima.
Kuvandudza Kushanda Kwekupisa
Kudzivirira kupisa kunomiririra imwe mukana wakakosha weupfu hwekaolin hwakagadziriswa pamusoro pechinhu mukushandiswa kwepurasitiki. Zvigadzirwa zvakawanda zvepurasitiki zvemazuva ano, zvinosanganisira mavharo emagetsi, zvikamu zvepasi pemotokari, uye zvinhu zvekuvaka, zvinofanirwa kutsungirira tembiricha yakakwira pasina kuora. Hunhu hwakawanda hwealumina (hunobva pa38%-42%) muupfu hwekaolin, pamwe chete nenzira dzinoshanda dzekugadzirisa pamusoro, zvinovandudza zvakanyanya tembiricha yekupisa (HDT) yemapurasitiki.
Mugadziri wePVC wekuItaly ane mukurumbira akashandisa upfu hwekaolin hwakagadziriswa pamusoro mukugadzira mahwindo, zvichiita kuti HDT iwedzere kubva pa70°C kusvika pa85°C. Kuvandudzwa uku kwekutsungirira tembiricha kunoita kuti maPVC frame agone kumira kwenguva refu achiratidzwa nezuva rakananga munzvimbo dzeMediterranean pasina kuchinjika kana kuchinja. Saizvozvowo, kune PP electrical enclosures dzinochengetedza zvikamu zvemagetsi zvinogadzira kupisa, kuiswa kwekaolin powder kwakasimudza HDT kubva pa110°C kusvika pa130°C, zvichisangana nezvinodiwa zvakanyanya zvekupisa. Pamusoro pezvo, upfu hunoderedza matambudziko ekupisa; Zvikamu zvePP zvakaumbwa nejekiseni zvine 15% kaolin powder zvakaratidza mwero wekuderedzwa kwe1.2%, zvichienzaniswa ne2.5% yePP isina kusimbiswa, zvichiita kuti zvive nechokwadi chekuti mativi acho akarurama panguva yekugadzira.
Maitiro Ekugadzira uye Magadzirirwo Ehunyanzvi
Kugadzirwa kweupfu hwekaolin hwakagadziriswa pamusoro pepurasitiki kunosanganisira maitiro maviri akagadzirwa zvakanaka: kunatswa kwesimbi uye kugadziriswa kwesimbi pamusoro. Matombo ekaolin asina kucheneswa anogadzirwa kuburikidza nekupatsanurwa kwemagineti uye nzira dzekugadzira froth flotation kubvisa tsvina yesimbi netitanium, izvo zvinogona kukanganisa mashandiro eupfu. Zvadaro, matombo anokuyiwa kusvika pahukuru hwechinhu chinodiwa uchishandisa nzira dzekukuya dzakaoma nemidziyo yekuisa mweya, zvichigadzira magiredhi anotangira pa1000 kusvika 2000 mesh.
Danho rekugadzirisa pamusoro rinoshandisa ma mixers anomhanya zvikuru anoshanda pa 1500-2000 rpm kuti apfekedze zvikamu zve kaolin zvakafanana nezvinobatanidza. Zvinobatanidza zve silane, zvakaita se KH-550, zvinofarirwa kushandiswa paPP ne PE nekuda kwekubatana kwazvo nema polyolefin polymers, nepo zvinobatanidza zve titanate zvakaita se TMC-101 zvakakodzera zvakanyanya kune PVC compounds. Chiyero chezvinobatanidza chinodzorwa nokungwarira pa 0.5%-1.5% yehuremu hwe kaolin powder kuitira kuti pave nechokwadi chekuti zvikamu zvakafukidzwa zvakakwana pasina zvinhu zvakawandisa zvinogona kukanganisa kugadzirwa kwepurasitiki. Mushure mekushandurwa, upfu hunotonhodzwa kusvika patembiricha yemhepo uye hunoseferwa kuti hubvise chero ma agglomerates, zvichiita kuti chigadzirwa chienderane, chakagadzirira kubatanidzwa muma formulations epurasitiki.
Zviratidzo zvikuru zvehunyanzvi zvinotonga mhando yeupfu hwekaolin hwakagadziriswa pamusoro pepurasitiki. Kugoverwa kwehukuru hwezvikamu, kwakayerwa neD50 values ye5-10 μm (1000 mesh) kana 2-5 μm (2000 mesh), kunokanganisa zvakananga kupararira uye kushanda kwekusimbisa. Kuchena, kunoratidzwa seL* value ye ≥90%, kunoita kuti runako ruenderane nemashandisirwo apo ruvara rwuri chinhu chakakosha. Kudzora hunyoro kwakasimba (≤0.3%) kunodzivirira matambudziko akadai sehydrolysis panguva yekugadzira purasitiki, nepo chiyero chekufukidza che coupling agent che ≥95% chichivimbisa kubatana kwakanaka kweinterfacial. Makoshero ekunyudzwa kwemafuta ari pakati pe20-25 mL/100g anoratidza hunhu hwekunyorovesa kweupfu, zvichikanganisa viscosity ye compound uye maitiro ekugadzirisa. Aya ma parameter anoedzwa zvakanyanya uchishandisa maturusi ekuongorora epamusoro, anosanganisira laser particle size analyzers, Fourier-transform infrared spectroscopy (FTIR), uye thermogravimetric analysis (TGA).
Kubudirira kweChain Yekugovera uye Rutsigiro rwehunyanzvi
Nzvimbo yekugovera zvinhu zveupfu hwekaolin hwakagadziriswa pamusoro pevhu yakagadziridzwa kuti ienderane nematanho ekugadzira eindasitiri yepurasitiki. Sarudzo dzekurongedza dzinosanganisira mabhegi epepa ane 25kg akawanda ane machira anodzivirira kuungana kweguruva uye kuona kuti chigadzirwa chakamira zvakanaka, pamwe nemabhegi akawanda e1000kg ane machira eforklift ekubata nekuchengetera zvinhu zvakanaka. Nguva dzekutumira dzinogadziriswa, nevatengi vemunzvimbo (semuenzaniso, zvinhu zvinotumirwa kubva kuChina kuenda kuSoutheast Asia) vachigamuchira maodha mukati memazuva 7-14, ukuwo zvinhu zvinotumirwa kunze kwenyika (zvakaita sezviri kuEurope) zvichipedzwa mukati memazuva 21-30.
Tsananguro yeChigadzirwa
Takaisa kaolin yakakangwa, kaolin yakagezwa, uye metakaolin.
Kaolin ine calcium, inozivikanwawo sevhu reporcelain, ine kuchena kwakanyanya, kupfava kwakanyanya, purasitiki yakanaka, uye ine ngura yakasimba
