Chotulutsira Chozungulira cha Mapawiri a Conical: Kufotokozera kwa Njira Yogulitsira

A chotulutsira chozungulira cha mapasa awirindi mtundu wa chotulutsira ma screw awiri chomwe chili ndi ma screw awiri okonzedwa mu mawonekedwe a conical, ochepera kumapeto kwa chotulutsira. Kapangidwe kameneka kamachepetsa pang'onopang'ono kuchuluka kwa njira ya screw, zomwe zimapangitsa kuti kupanikizika kuchuluke komanso kupangika bwino. Chotulutsira ma screw awiri a conical chimapangidwa makamaka ndi screw ya barrel, gear transmission system, quantitative feeding, vacuum exhaust, heating, cooling and electrical control components.

Chotulutsira ma screw awiri chozungulira ndi choyenera kupanga zinthu za PVC kuchokera ku ufa wosakaniza. PVC ndi polima ya thermoplastic yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana, monga zomangamanga, kulongedza, zamagetsi, zamagalimoto, ndi zamankhwala. Komabe, PVC sigwirizana ndi ma polima ena ambiri ndi zowonjezera, ndipo imafuna njira zapadera zokonzera kuti ikwaniritse mawonekedwe ndi magwiridwe antchito omwe akufunidwa. Chotulutsira ma screw awiri chozungulira chingapereke kusakaniza, kusungunula, kuwononga, ndi kufananiza PVC ndi zowonjezera zake mosalekeza komanso moyenera.

Chotulutsira ma screw awiri okhala ndi conical ndi chida chapadera chotulutsira ufa wa WPC. WPC imayimira matabwa ndi pulasitiki, chomwe ndi chinthu chomwe chimaphatikiza ulusi wamatabwa kapena ufa wamatabwa ndi ma polima a thermoplastic, monga PVC, PE, PP, kapena PLA. WPC ili ndi ubwino wa matabwa ndi pulasitiki, monga mphamvu yayikulu, kulimba, kukana nyengo, komanso kubwezeretsanso. Chotulutsira ma screw awiri okhala ndi conical chimatha kukonza ufa wa WPC ndi mphamvu yayikulu, kugwira ntchito mokhazikika, komanso nthawi yayitali yogwira ntchito.

Ndi zipangizo zosiyanasiyana za nkhungu ndi zapansi pa madzi, chotulutsira ma screw awiri chozungulira chingapange zinthu zosiyanasiyana za PVC ndi WPC, monga mapaipi, denga, ma profiles a zenera, mapepala, ma decking, ndi ma granules. Zogulitsazi zili ndi mawonekedwe osiyanasiyana, kukula, ndi ntchito zosiyanasiyana, ndipo zimatha kukwaniritsa zosowa zosiyanasiyana za makasitomala ndi misika.

Kufotokozera kwa Njira

Njira yotulutsira ma screw awiri a conical ikhoza kugawidwa m'magawo anayi akuluakulu: kudyetsa, kusungunula, kuwononga, ndi kupanga mawonekedwe.

Kudyetsa

Gawo loyamba la kutulutsa ma screw awiri a conical ndi kudya. Mu gawoli, zinthu zopangira, monga ufa wa PVC kapena WPC, ndi zina zowonjezera, monga zokhazikika, mafuta odzola, zodzaza, utoto, ndi zosinthira, zimayesedwa ndikulowetsedwa mu extruder ndi zida zosiyanasiyana zodyetsera, monga ma screw auger, ma vibratory trays, ma weigh-lambs, ndi ma injection pumps. Kuchuluka kwa chakudya ndi kulondola ndi zinthu zofunika kwambiri zomwe zimakhudza ubwino ndi kusinthasintha kwa zinthu zomaliza. Zinthu zopangira zimatha kusakanikirana ndi kudyetsedwa, kapena padera komanso motsatizana mu extruder, kutengera kapangidwe kake ndi mawonekedwe omwe mukufuna a zinthuzo.

Kusungunuka

Gawo lachiwiri la kutulutsa kwa screw ziwiri za conical likusungunuka. Pa gawoli, zipangizo zopangira zimatumizidwa, kuponderezedwa, ndikutenthedwa ndi zomangira zozungulira ndi zotenthetsera za barrel, ndikusinthidwa kuchoka pamlingo wolimba kupita ku wamadzimadzi. Njira yosungunula imaphatikizapo mphamvu ya kutentha ndi yamakina, ndipo imakhudzidwa ndi liwiro la screw, kapangidwe ka screw, kutentha kwa barrel, ndi mawonekedwe a zinthu. Njira yosungunula ndiyofunikanso pakufalikira ndi kufalikira kwa zowonjezera mu polymer matrix, komanso kuyambitsa machitidwe a mankhwala, monga cross-linking, grafting, kapena degradation, omwe angachitike mu kusungunuka. Njira yosungunula iyenera kuyendetsedwa mosamala kuti ipewe kutentha kwambiri, kumeta kwambiri, kapena kusungunuka kwa zinthuzo, zomwe zingayambitse khalidwe loipa la mankhwala ndi magwiridwe antchito.

Kuwononga chilengedwe

Gawo lachitatu la kutulutsa ma screw awiri a conical ndi devolatilization. Mu gawoli, zinthu zosinthasintha, monga chinyezi, mpweya, ma monomers, zosungunulira, ndi zinthu zowola, zimachotsedwa mu kusungunuka mwa kugwiritsa ntchito vacuum pamadoko otulukira mpweya omwe ali pafupi ndi mbiya yotulutsira mpweya. Njira yochotsera mpweya ndi yofunika kwambiri kuti zinthu zikhale bwino komanso zokhazikika, komanso kuchepetsa kuwonongeka kwa chilengedwe komanso zoopsa paumoyo wa njira yochotsera mpweya. Njira yochotsera mpweya imadalira kapangidwe ka ma screw, kuchuluka kwa vacuum, kukhuthala kwa kusungunuka, ndi mawonekedwe a zinthu. Njira yochotsera mpweya iyenera kukonzedwa bwino kuti ichotse mokwanira ma screw popanda kuyambitsa thovu lochuluka, kusefukira kwa mpweya, kapena kuwonongeka kwa kusungunuka.

Kupanga

Gawo lachinayi komanso lomaliza la kutulutsa ma screw awiri a conical likupangika. Mu gawoli, kusungunuka kumatulutsidwa kudzera mu die kapena nkhungu yomwe imasankha mawonekedwe ndi kukula kwa chinthucho. Die kapena nkhunguyo ikhoza kupangidwa kuti ipange zinthu zosiyanasiyana, monga mapaipi, ma profiles, pepala, filimu, kapena ma granules. Njira yopangira imakhudzidwa ndi geometry ya die, kuthamanga kwa die, kutentha kwa die, ndi rheology yosungunuka. Njira yopangira iyenera kusinthidwa kuti ikwaniritse ma extrudates ofanana komanso osalala opanda zolakwika, monga kutupa kwa die, kusweka kwa kusungunuka, kapena kusakhazikika kwa dimensional. Pambuyo pa njira yopangira, ma extrudates amaziziritsidwa, kudula, ndikusonkhanitsidwa ndi zida zotsika, monga ma calibrator, ma haul-offs, ma cutter, ndi ma winders.

Mapeto

Chotulutsira ma screw awiri chozungulira ndi chipangizo chogwira ntchito bwino komanso chothandiza popanga zinthu za PVC ndi WPC kuchokera ku ufa wosakaniza. Chimapereka ntchito zofunika pakudyetsa, kusungunula, kuwononga, ndi kupanga zinthu mosalekeza komanso molamulidwa. Chingathenso kupanga zinthu zosiyanasiyana zokhala ndi mawonekedwe, kukula, ndi ntchito zosiyanasiyana, pogwiritsa ntchito zipangizo zosiyanasiyana za nkhungu ndi zapansi. Chotulutsira ma screw awiri chozungulira chili ndi ubwino wokhala ndi ma composite abwino, kutulutsa kwakukulu, kugwira ntchito mokhazikika, komanso kukhala ndi moyo wautali, ndipo chimatha kukwaniritsa zosowa zosiyanasiyana za makasitomala ndi misika.
