Matumba opaka pulasitiki amapangidwa ndi polypropylene (PP) monga zida zazikulu, zomwe zimatulutsidwa, zokoka zitsulo, zolukanso, zoluka, ndikupangidwa kukhala matumba onyamula.
PP ndi mandala, theka-crystalline thermosetting pulasitiki ndi kulimba kwambiri, katundu wabwino kutchinjiriza, mayamwidwe otsika madzi, kutentha yozungulira, otsika kachulukidwe wachibale, ndi kutentha mkulu galasi.Ndilo chopangira chachikulu chopangira matumba oyikamo.Zida zosinthidwa zosinthidwa nthawi zambiri zimakhala ndi ulusi wamagalasi, zida zodzaza mchere, mphira wa thermoplastic, ndi zina zotero.
Kuchuluka kwa matumba oyikapo pulasitiki ndikotambasula kwambiri.Panthawi imeneyi, ntchito kiyi matumba pulasitiki ma CD ndi ma CD akunja a katundu ulimi, ma CD akunja matumba nsalu pulasitiki, chakudya ma CD zipangizo, zomangamanga zomangamanga, holide zoyendera alendo, kulimbana kusefukira ndi zinthu mwadzidzidzi, etc. Pali atatu. mitundu ikuluikulu ya matumba olongedza: matumba apulasitiki (matumba opanda mafilimu), matumba apulasitiki ophatikizika ndi zikwama zosiyanasiyana zoluka.Njira yopanga matumba opangira pulasitiki ndi: matumba oluka amakhala matumba onyamula pambuyo pakulongedza ndi kusindikiza, kudula ndi kusoka kwa laser.
Malinga ndi makina ndi zipangizo ntchito, akhoza laser kudula ndiyeno kusindikizidwa, kapena kusindikizidwa ndiyeno laser kudula.Makina osokera a laser okha amatha kupitiliza njira yosindikizira, kudula laser, makina osokera, etc., ndipo amathanso kupangidwa m'matumba a valve, matumba apansi, etc. thumba akhoza kupangidwa.Njira yopangira matumba apulasitiki ophatikizika ndikuyika zikwama zoluka, miyala yophatikizika kapena mafilimu kuti muyanjanitse kapena zokutira zophatikiza.Mipukutu yopezedwa kapena mapepala ndi masikono amatha kudulidwa ndi laser, kupakidwa ndi kusindikizidwa ndikusokedwa opaleshoni kuti apange matumba apansi amsoko.Amathanso kutsegula mabowo, crimping m'mphepete, kudula laser, kusindikiza ma CD, kusoka opaleshoni ndi zikwama zapulasitiki.Pepala lomwe mwapeza limatha kumamatidwa ndi msoko, kusindikiza kwa phukusi, kudula kwa laser, kulumikiza chivundikiro ndi thumba la phala.Ithanso kuwotcherera, kuyika, crimped, kupangidwa kukhala mashedi amatabwa ndi ma geotextiles osalukidwa.Zovala zosalala zimatha kukhala zobwerezabwereza kapena zosabwerezabwereza komanso kupanga, zosapanga ma geotextiles, etc. Nsalu ya ng'oma imatha kupangidwanso mobwerezabwereza kapena ayi.
Zizindikiro za ntchito yopanga makina opangira makina apulasitiki amagawidwa m'magulu anayi:
1. Physical performance index value.Pali makamaka zolakwika zamagulu monga kuthyola mphamvu, mphamvu yosweka, mphamvu yokhazikika, kuthamanga kwa angular, ndi kachulukidwe;
2. Mndandanda wazinthu zosinthidwa ndi organic.Zimaphatikizapo kusakaniza zipangizo zosinthidwa, kukonzekera kusakaniza, kuwonjezera chiŵerengero cha zosintha, ndi chiŵerengero cha zinyalala zowonongeka granular pawiri fetereza;
3. Dimensional tolerance specification index value.Zimaphatikizapo makulidwe a makina ojambulira mawaya apulasitiki ndi m'lifupi mwa waya wophwanyika.
4. Thupi katundu rheological index mtengo.Pali makamaka chiŵerengero chogawanika cha ulusi, chiŵerengero cha inflation, chiŵerengero cha kusalinganika ndi chiŵerengero cha kuchepa;
Mzere thumba processing luso High kuthamanga polyethylene zakuthupi ndi usavutike mtima ndi extruder, anasungunuka ndi extruded bwino;
Kanikizani pulasitiki yooneka ngati mbiya mufilimu yapulasitiki yooneka ngati mbiya;kulowa kuchepetsa kuwomba fumbi ndi chifukwa chubu thovu;
Tsitsi lowongolera tsitsi lopangidwa ndi herringbone limakhazikika ndikuwumbidwa ndi mphete ya mpweya woziziritsa, ndipo kukoka kumabweretsedwa kutembenuka;
The galimoto dongosolo wodzigudubuza kukokedwa kwa wodzigudubuza yokhotakhota kudzera traction lamba wodzigudubuza;
Pomaliza, kudula kwa laser kumachitika, thumba lazitsulo limapangidwa ndi njira yotentha yosungunuka, ndipo pamapeto pake chipatsocho chimayikidwa.
Polypropylene yoyera siyingakwaniritse zosowa zamakina ojambulira mawaya apulasitiki, koma ikufunikanso kuwonjezera gawo lina la polyethylene, calcium bicarbonate ndi color masterbatch.Kuwonjezera pang'ono polyethylene pa lonse extrusion ndondomeko akhoza kuchepetsa mamasukidwe akayendedwe ndi kusungunuka mlingo wa zinthu otaya, kusintha fluidity, kusintha ductility ndi kusinthasintha kwa makina pulasitiki waya kujambula ndi matumba ma CD pulasitiki, kukhalabe ena amakokedwe mphamvu, ndi onjezerani kuwonongeka kwa kutentha kwa polypropylene kopitilira muyeso.
Zowonjezera zowonjezera za polypropylene zimatha kuchepetsa kutentha ndi kupanikizika kwa ntchito popanga ndi kukonza malo.Limbikitsani kuyenda kwa data ndi kumamatira, onjezerani mphamvu zamakokedwe.Kuwonjezera kwa calcium bicarbonate kungasinthe zofooka za kuwonekera kwathunthu ndi kuwala.Pochepetsa kutambasula, njira yonseyi imawononga kuyika kwa electrostatic chifukwa imawononga mikangano, kuwongolera kumamatira kwa inki yosindikizira ndikusindikiza ma logos, kuchepetsa kusonkhanitsa kwachilengedwe ndikuwongolera mtengo wazinthu zomalizidwa panthawi yosungira.
