Non nsalu thumba zopangira

Zipangizo zopangira matumba osaluka

Matumba osalukidwa amapangidwa ndi nsalu zosalukidwa ngati zopangira. Nsalu zosalukidwa ndi mbadwo watsopano wa zipangizo zoteteza chilengedwe zomwe zimateteza chinyezi, zopumira, zosinthika, zopepuka, zosapsa, zosavuta kuwonongeka, zopanda poizoni komanso zosakwiyitsa, zolemera mumtundu, zotsika mtengo, komanso zogwiritsidwanso ntchito. Izi zimatha kuwola mwachilengedwe zitayikidwa panja kwa masiku 90, ndipo zimakhala ndi moyo wautumiki mpaka zaka 5 zikayikidwa m'nyumba. Akawotchedwa, alibe poizoni, alibe fungo, ndipo alibe zinthu zotsalira, motero samawononga chilengedwe. Imazindikiridwa padziko lonse lapansi ngati chinthu chosakonda zachilengedwe poteteza zachilengedwe zapadziko lapansi.

Pali zida ziwiri zazikulu zopangira matumba osaluka, imodzi ndi polypropylene (PP), ndipo ina ndi polyethylene terephthalate (PET). Zida zonsezi ndi mtundu wa nsalu zopanda nsalu, zopangidwa ndi ulusi kudzera muzitsulo zotentha kapena kulimbitsa makina, ndi mphamvu zambiri komanso ntchito yabwino yopanda madzi.

Polypropylene (PP): Izi ndizofalansalu zopanda nsalundi kukana kwabwino kwa kuwala, kukana dzimbiri, komanso kulimba kwamphamvu. Chifukwa cha mawonekedwe ake asymmetric komanso kukalamba kosavuta komanso kusiyanitsa, matumba omwe sanalukidwe amatha kukhala oxid ndikuwola mkati mwa masiku 90.

Polyethylene terephthalate (PET): yomwe imadziwikanso kuti polyester, matumba osaluka amtunduwu ndi olimba, koma poyerekeza ndi polypropylene, mtengo wake wopanga ndi wokwera.

Kugawika kwa matumba osaluka

1. Chinthu chachikulu cha matumba osapangidwa ndi nsalu zopanda nsalu. Nsalu zosalukidwa ndi mtundu wansalu wosalukidwa womwe ndi mtundu watsopano wamtundu wa ulusi wofewa, wopumira, komanso wosalala womwe umapangidwa pogwiritsa ntchito tchipisi tambiri ta polima, ulusi wamfupi, kapena ulusi wautali kudzera munjira zosiyanasiyana zopangira mauna ndi njira zophatikizira. Ubwino wake: Matumba osalukidwa ndi otsika mtengo, okonda zachilengedwe komanso othandiza, amagwiritsidwa ntchito kwambiri, ndipo amakhala ndi malo otchuka otsatsa. Zoyenera kuchita bizinesi ndi ziwonetsero zosiyanasiyana, ndi mphatso yabwino yotsatsira mabizinesi ndi mabungwe.

2. Zopangira nsalu zopanda nsalu ndi polypropylene, pamene zopangira matumba apulasitiki ndi polyethylene. Ngakhale kuti zinthu ziwirizi zili ndi mayina ofanana, mankhwala ake ndi otalikirana. Mapangidwe a molekyulu a polyethylene ali ndi kukhazikika kwamphamvu ndipo ndizovuta kwambiri kunyozeka, motero matumba apulasitiki amatenga zaka 300 kuti awole kwathunthu; Komabe, mawonekedwe a mankhwala a polypropylene sali olimba, ndipo maunyolo a molekyulu amatha kusweka mosavuta, omwe amatha kuwononga bwino ndikulowa mkombero wotsatira wachilengedwe mopanda poizoni. Thumba losalukidwa limatha kuwola mkati mwa masiku 90.

Malingana ndi njira zosiyanasiyana zopangira, zikhoza kugawidwa

1. Kupota: Ndi njira yopopera madzi abwino kwambiri amphamvu kwambiri pagawo limodzi kapena zingapo za fiber mesh, zomwe zimapangitsa kuti ulusiwo ulumikizike ndikulimbitsa mauna kumlingo wina wake wamphamvu.

2. Thumba losindikizidwa lopanda nsalu: limatanthauza kuwonjezera zomatira zomata za ulusi kapena ufa wonyezimira ku mauna a ulusi, kenako kutenthetsa, kusungunula, ndi kuziziritsa mauna a CHIKWANGWANI kuti awulimbikitse kukhala nsalu.

3. Pulp airflow net thumba lansalu losalukidwa: limadziwikanso kuti pepala lopanda fumbi kapena kupanga pepala louma lopanda nsalu. Imagwiritsa ntchito ukadaulo wa ma airflow mesh kumasula bolodi lazamkati lamatabwa kukhala ulusi umodzi, kenako imagwiritsa ntchito njira ya airflow kuphatikizira ulusi pa nsalu yotchinga, ndipo mauna a fiber amalimbikitsidwa. 4. Thumba lonyowa lansalu losalukidwa: Ndi njira yomasulira zinthu zopangira ulusi zomwe zimayikidwa mu sing'anga yamadzi kukhala ulusi umodzi, ndikusakaniza zida zopangira ulusi kuti zipangitse slurry ya kuyimitsidwa kwa ulusi. Kuyimitsidwa slurry kumatumizidwa ku makina opangira ukonde, ndipo ulusiwo umalimbikitsidwa kukhala nsalu mumkhalidwe wonyowa.

5. Spin zomangira nsalu zosalukidwathumba: Ndi njira imene polima wakhala extruded ndi anatambasula kupanga mosalekeza ulusi, amene kenako anaika mu ukonde. Kenako ukonde umadzimangiriza pawokha, womangiriridwa ndi thermally, womangidwa ndi mankhwala, kapena kumangirizidwa mwamakina kuti usanduke nsalu yosalukidwa.

6. Sungunulani thumba la nsalu yopanda nsalu: Njira yake imaphatikizapo kudyetsa polima - kusungunula extrusion - kupanga CHIKWANGWANI - kuzizira kwa fiber - kupanga mauna - kulimbikitsanso mu nsalu.

7. Acupuncture: Ndi mtundu wa nsalu zouma zosalukidwa zomwe zimagwiritsa ntchito kubowola kwa singano kulimbitsa mauna a ulusi wa fluffy mu nsalu.

8. Kuluka: Ndi mtundu wa nsalu zowuma zosalukidwa zomwe zimagwiritsa ntchito cholumikizira choluka choluka kuluka ulusi, zigawo za ulusi, zinthu zosalukidwa (monga mapepala apulasitiki, zitsulo zopyapyala za pulasitiki, ndi zina zotero) kapena magulu awo.
