1. Nhanganyaya yeMabhegi Akarukwa uye Tekinoroji Yekugadzirisa Kwawo
Mabhegi akarukwa epurasitiki anonyanya kugadzirwa ne polypropylene (PP), inogadzirwa kuburikidza ne extrusion, filament drawing, weaving, uye mabhegi. PP ipurasitiki inopenya zvishoma, ine simba guru, insulation yakanaka, inonyungudutsa mvura shoma, inopisa zvakanyanya, ine low density, uye ine crystallinity yakawanda, zvichiita kuti ive chinhu chikuru chekugadzira mabhegi akarukwa. Mafiller akagadziriswa anowanzo sanganisira girazi fiber, mineral fillers, uye thermoplastic raber.
Mabhegi akarukwa epurasitiki ane mabasa akasiyana-siyana. Parizvino, anonyanya kushandiswa pakurongedza zvigadzirwa zvekurima, kurongedza mabhegi esimende, kurongedza chikafu, mainjiniya epasi, kutakura vanhu, uye zvinhu zvekudzivirira mafashamo.
Mabhegi akarukwa anonyanya kuiswa muzvikamu zvitatu: mabhegi akarukwa epurasitiki (mabhegi akarukwa asina laminated), mabhegi akarukwa epurasitiki akabatanidzwa, uye machira akasiyana-siyana akarukwa.
Maitiro ekugadzira mapurasitikimabhegi akarukwandeinotevera: jira rakarukwa rinodhindwa, rinochekwa, uye rinosonerwa kuti rive mabhegi akarukwa. Zvichienderana nemidziyo inoshandiswa, kucheka kunogona kuitwa usati wadhinda, kana kudhinda kunogona kuitwa usati wadhinda. Kucheka nekusona otomatiki kunogona kupedzisa maitiro ekudhinda, kucheka, uye kusona nguva dzose. Inogona zvakare kugadzira mabhegi evharuvhu, mabhegi anozadzwa pasi, nezvimwewo. Kune machira akarukwa asina kurongeka, kubatana kwepakati-nemusono kunogona kuitwa usati wagadzira mabhegi.
Maitiro ekugadzira compositemabhegi epurasitiki akarukwazvinosanganisira kuputira jira rakarukwa, zvinhu zvekuputira, uye bepa kana firimu. Jira rinobuda rinogona kuchekwa, kudhindwa, uye kusonwa kuti rigadzire mabhegi akajairwa ekusonerwa. Rinogonawo kubhombwa, kuchekwa, kuchekwa, kudhindwa, uye kusonwa kuti rigadzire mabhegi esimende. Jira rinobuda rinogona kunge riri pakati nepakati, rakadhindwa, rakachekwa, uye rakanamirwa pasi kuti rigadzire mabhegi ane glue-pasi. Rinogonawo kusungirirwa uye kumonerwa kuti rigadzire matarpaulins uye geotextiles.
Machira akarukwa asina kuvharwa anogona kuputirwa kana kusaputirwa kuti agadzire matende, majeti, nezvimwewo. Machira eTubular anogonawo kubvaruka nekuputirwa kana kusaputirwa kuti agadzire matende kana majeti, nezvimwewo.
2. Nzira dzekugadzirisa Bhegi Rakarukwa uye Matekiniki
2.1 Kuumbwa kwezvikamu
Kuumbwa kwepurasitiki idanho rakakosha pakugadzirwa kwepurasitiki. Zvinhu zvakawanda zvepurasitiki zvinoda kuumbwa mushure mekugadzirwa kwepurasitiki zvisati zvashandiswa, uye tekinoroji iyi inokanganisa zvakananga kunaka kwezvigadzirwa zvepurasitiki. Maitiro makuru ekugadzirwa kwepurasitiki anosanganisira: kuumbwa, kubudiswa, kusefa, kutonhodza mvura, kudhonza, kuomesa, uye kurongedza.
Upfu hwepolypropylene, zvimwe zvinowedzerwa zvakasiyana-siyana, uye calcium carbonate yakabatidzwa zvinowedzerwa kumuchina wekusanganisa unomhanya zvakanyanya muchikamu chakati uye mumutsara chaiwo. Mushure mekusanganisa nekukurumidza kusvika pakumhanya kwenguva yakati, musanganiswa wacho unoiswa muhopper uye unotakurwa nescrew feeder. Zvinhu izvi zvinopinda mubharero kuburikidza nefeed inlet, uko zvinonyungudutswa uye zvinoiswa purasitiki nebarrel nescrew, zvichiramba zvichiburitswa kuita strips. Mitsetse yacho inotonhodzwa uye inoumbwa mutangi remvura, yozobviswa hunyoro nefeni inobvisa hunyoro, yotonhodzwa nefeni, uye yozoiswa pelletizer nepelletizer. Mushure mekuongororwa nescreen inodedera, mitsetse yacho inotakurwa nefeni inoendesa kumubhedha une mvura kuti iome. Pakupedzisira, mitsetse yacho inopinda mutangi rezvinhu, uye feeder inosveta zvinhu kubva mutangi kuenda mutangi rekuchengetera. Mushure mekunge mapellets apasa kuongororwa, anoiswa mupakeji yakawanda, zvichipedzisa maitiro ese ekugadzira. 2.2 Kudhirowa kweYarn Kudhirowa kweYarn, kunozivikanwawo seflat yarn drawing kana fiber cutting, inzira yakakosha mumitsetse yekugadzira mabhegi akarukwa; Saizvozvowo, chiyuniti chekudhirowa shinda ndicho chinhu chikuru chefekitori yekugadzira mabhegi akarukwa. Hunhu hwemaitiro ekudhirowa shinda hunokanganisa zvakananga kunaka kwemukati nekunze kwechigadzirwa.
Maitiro eshinda yakatsetseka anosanganisira: kugadzirisa zvinhu zvisina kugadzirwa, kusanganisa, kupenda, kuzadza, kugadzira, kudzivirira kukwegura uye kuora, tembiricha, kumanikidzwa, uye kudzora mwero wekuyerera kwemvura panguva yekubuda, maitiro e rheological panguva yekubuda, mashandisirwo esimba nematambudziko egoho, chiyero chekudhonza, chiyero chekuputira, chiyero chekudhonza, kutonhora kwekristaro, kutarisa, kurapwa kwekupisa uye nyaya dzekuumba, kuumbwa panguva yekumonera, uye kuongororwa kwemhando yeshinda.
Mushure mekunge zvinhu zvakabikwa zvapinda mu extruder, zvinopiswa nekunze pa 190-250℃ uye zvinochekwa pakati pe screw nebarrel. Mushure mekunge zvanyatsogadzirwa nepurasitiki, zvinhu zvinobudiswa zvine huwandu uye zvichimanikidzwa nguva dzose. Mushure mekunge zvagadzirwa pamusoro we die, zvinova firimu rakanyungudutswa rinopinda mumvura inotonhorera. Mushure mekutonhorera, firimu rinochekwa kuita filaments nemablades. Filaments dzinozotambanudzwa pakupisa kwakanyanya muovheni inodziya zvakanyanya kusvika dzaita shinda dzakatsetseka. Shinda yakatsetseka inozoiswa pakupisa pama hot rollers, yotanga kuderera nekumhanya kwakaderera kwekukweva, uye inogadziriswa pakupisa kwakaderera nema cold rollers. Pakupedzisira, inoputirwa kuita chimiro ne differential tension winding system.
Maitiro ekugadzira shinda dzakatsetseka anogona kurongwa nenzira yekugadzira firimu (chubhu firimu, firimu rakatsetseka); nenzira yekutonhodza mushure mefirimu (kutonhodza mhepo, kutonhodza mvura, uye kutonhodza nguva nenguva); nenzira yekunyora nekudziisa (hot plate, hot rollers, mhepo inopisa); uye nenzira yespindle winding (centralized cycloidal winding, single-spindle torque motor winding, uye magnetic torque winding).
