Iplastikiiingxowa ezilukiweyozenziwe nge-polypropylene (PP) njengeyona nto iphambili, kwaye zenziwe nge-extrusion, i-wire drawing, i-weaving, i-knitting kunye ne-bag making.
I-Polypropylene yi-thermoplastic eguquguqukayo kunye ne-semi-crystalline thermoplastic enamandla amakhulu, ukugquma okulungileyo, ukufunxa kwamanzi aphantsi, ubushushu obuphezulu be-thermoforming, ubuninzi obuphantsi kunye nekristali ephezulu.Yeyona nto iphambili yeengxowa ezilukiweyo.Izihluzi ezilungisiweyo zibandakanya iifiber zeglasi, izihluzi zeminerali, irabha ye-thermoplastic, kunye nokunye.
Iingxowa zeplastiki eziphothiweyo zineendlela ezininzi zokusetyenziswa.Okwangoku, iingxowa eziphothiweyo zeplastiki zisetyenziselwa ukupakishwa kwemveliso yezolimo, ukupakishwa kweengxowa zesamente, ukupakishwa kokutya, ubunjineli be-geotechnical, uthutho lokhenketho, izixhobo zokulawula izikhukhula, njl njl. iingxowa kunye namalaphu ahlukeneyo alukiweyo.Inkqubo yokuveliswa kweengxowa ezilukiweyo zeplastiki yile ilandelayo: ukuluka ukuprinta, ukusika, nokuthunga kwiingxowa ezilukiweyo.
Kuxhomekeka kwisixhobo esisetyenziswayo, inokusikwa kuqala ize iprintwe, okanye iprintwe ize isikwe.Abathungi abazenzekelayo banokuqhubeka begqibezela ukuprinta, ukusika, ukuthunga kunye nezinye iinkqubo, kwaye kunokwenziwa kwiipokotho zevalve, iipokotho ezisezantsi, njl.Inkqubo yemveliso yeengxowa ezilukiweyo zeplastiki kukudibanisa okanye ukugquma amalaphu alukiweyo, izinto zokugquma kunye nephepha okanye ifilimu.Umbhobho obangelwayo okanye iqhekeza lelaphu linokunqunyulwa, liprintwe, lithungwe kwaye lenziwe libe yingxowa yomthungo ephantsi eqhelekileyo, okanye ibhotshwe, isongwe, isikwe, iprintwe kwaye ithungelwe kwingxowa yesamente, kunye neqhekeza elifunyenweyo lelaphu lingaba Ukuthunga, ukuncamathelisa, ukuprinta, ukusika kunye nokuncamathelisa kwiipokotho ezisezantsi.Inokuthi idityaniswe kwaye iqengqeleke ukwenza iiseyile kunye ne-geotextiles.Ilaphu elingenanto linokuthi ligqunywe okanye lingagqunywanga ukuze livelise iitarpaulins, i-geotextiles, njl.
Izalathi zobugcisa zenkqubo yokuvelisa ucingo olusicaba zahlulwe ikakhulu ngokweendidi ezine:
1. Isalathisi sokusebenza koomatshini.Ikakhulu ibandakanya amandla e-tensile, amandla okuqina ahambelanayo, ukwanda ngexesha lekhefu, isantya somgca, ukutenxa koxinaniso;
2. Isalathisi sokuguqulwa komzimba kunye neekhemikhali.Kukho ubukhulu becala ukuguqulwa kokudibanisa, umlinganiselo wokudibanisa, umlinganiselo wokudibanisa osebenzayo, kunye nomlinganiselo wokudibanisa wenkunkuma kunye nezinto ezihlaziyiweyo;
3. Isalathisi somda wokunyamezela.Kukho ubukhulu becala ubungqingqwa bocingo olusicaba, ububanzi bocingo olusicaba njalo njalo.
4. Physical rheological index.Kukho ubukhulu becala umlinganiselo wedrafti, umlinganiselo wokwandiswa, umlinganiselo oyidrafti kunye nomlinganiselo wokurhoxiswa;
Izinto ze-polyethylene kwi-bag lining process ziyafudumala, zinyibilike, zenziwe ngeplastiki kwaye zikhutshwe ngokusisigxina nge-extruder;
Cinezela kwifilimu ye-cylindrical ngentloko yokufa;ukwazisa igesi ecinezelweyo ukwandisa ukwenza amaqamza e-tubular;
Sebenzisa indandatho yokupholisa umoya ukupholisa kunye nokuma, tsala i-herringbone splint kwaye uyisonge;
Ngokusebenzisa iirola zokutsala, iirola zokuqhuba kunye neeroli ezijikajikayo,
Ekugqibeleni, inkqubo yokusika kunye nokutywinwa kobushushu iqhutyelwa ukugqiba ukuveliswa kwesikhwama sangaphakathi sangaphakathi, kwaye ekugqibeleni isikhwama sizaliswe.
I-polypropylene ecocekileyo yokuvelisa umsonto osicaba ayikwazi ukuhlangabezana neemfuno, kwaye inxalenye ethile ye-polyethylene ephezulu yoxinzelelo, i-calcium carbonate kunye ne-masterbatch yombala kufuneka yongezwe.Ukongeza inani elincinci loxinzelelo oluphezulu lwe-polyethylene kunokunciphisa i-viscosity kunye nesantya sokunyibilika kokuhamba kwezinto ngexesha lokukhupha, ukonyusa umbane, ukuphucula ukuqina kunye nokuthamba komsonto osicaba kunye nebhegi elukiweyo, gcina ubude obuthile ngexesha lekhefu, kwaye uphucule ubuncinci. impembelelo yobushushu bepolypropylene..
Ukongezwa kwepolypropylene egxunyekiweyo kunokunciphisa ubushushu bokusebenza kunye noxinzelelo.Ukuphucula ukuhamba kwezinto kunye nokubambelela, kwaye kwandisa amandla okuqina.Ukongezwa kwe-calcium carbonate kunokutshintsha iziphene zokungafihli kunye nokungafihli, ukunciphisa umbane ongatshintshiyo onobungozi oveliswa kukukhuhlana ngexesha lokwelula kunye nokuluka, ukwandisa inki yokuncamathela kwiipatheni zeempawu zokuthengisa eziprintiweyo, kunye nokunciphisa ukucutheka kwendalo kweemveliso ezigqityiweyo ngexesha lokugcinwa.
