Isiri yakarukwa polypropylene vs polyester

Machira asina kurukwa haasi machira akarukwa, asi anoumbwa neanotariswa kana asina kurongeka faibha marongero, saka anonziwo machira asina kurukwa. Nekuda kwezvakasiyana zvigadzirwa uye maitiro ekugadzira, machira asiri akarukwa anogona kupatsanurwa mumhando dzakawanda, sengemachira epolyester asina kuruka, polypropylene machira asina kuruka, nezvimwe.

Vatengi vanowanzo bvunza nezve mutsauko uripo pakati pe polyester isiri-yakarukwa jira, polypropylene isiri-yakarukwa jira, polypropylene faibha, uye polyester kana uchibvunza asiri akarukwa machira. Pazasi pane rondedzero yekusiyana kwavo.

PET isina-yakarukwa jira

PET spunbond filament jira risiri rakarukwa imhando yejira rinodzinga mvura risiri rakarukwa, uye kuita kwayo kwekudzingira mvura kunosiyana zvichienderana nehuremu hwejira. Iyo yakakura uye yakakora huremu, zviri nani kuita basa rekudzivirira mvura. Kana paine madonhwe emvura pamusoro pejira risiri rakarukwa, madonhwe emvura anotsvedza zvakananga kubva pamusoro.

Polyester isiri-yakarukwa jira inoshingirira kune yakanyanya kupisa. Nekuda kwekunyungudika kwepolyester kutenderedza 260 ° C, inokwanisa kuchengetedza kugadzikana kwezviyero zvekunze zvemachira asiri akarukwa munzvimbo dzinoda tembiricha. Yakave ichishandiswa zvakanyanya mukupisa kutamisa kudhinda, kusefa kwemafuta ekutepfenyura, uye zvimwe zvakaumbwa zvinhu zvinoda kupisa kwakanyanya.

PET spunbond isiri-yakarukwa jiraimhando yejira risiri rakarukwa rechipiri kune naironi spunbond jira risiri rakarukwa. Simba rayo rakanakisa, kupenya kwemhepo, kusimba, kuramba kubvarura uye anti-kuchembera zvinhu zvakashandiswa munzvimbo dzakasiyana siyana nevanhu vakawanda.

PET spunbond jira risiri-rakarukwa zvakare rine chinhu chakakosha chemuviri: kuramba kune gamma mwaranzi. Kureva kuti, kana ikaiswa kune zvigadzirwa zvekurapa, gamma mwaranzi inogona kushandiswa zvakananga kuuraya hutachiona pasina kukuvadza maitiro avo emuviri uye kugadzikana kwedimensional, inova pfuma yenyama iyo polypropylene (PP) spunbond isina-yakarukwa machira haana.

Polypropylene isiri-yakarukwa jira

Mucheka wakapetwa usiri wakarukwa unoreva tambo inoenderera inoumbwa neextrusion uye kutambanudza mapolymers, ayo anoiswa muwebhu. Dandemutande rinobva razvisungirira, rinosungwa nemoto, rakasungwa nemakemikari kana kusimbiswa nemuchina kuti dandemutande rive jira risiri rakarukwa. Rinoshandiswa pazvinhu zvinoraswa zvehutsanana, senge machira ehutsanana, machira ekuvhiya, ngowani, masks, machira, machira, nezvimwe. Machira ehutsanana evakadzi atova mapedhi evana emazuva ese anoraswa.

Isiri yakarukwa polypropylene vs polyester

PP i polypropylene raw material, kureva polypropylene fiber, inova yemucheka mutete usina kuruka; PET imhando nyowani yepolyester raw material, iyo inonzi polyester fiber, isina zvekuwedzera mukuita kwese kwekugadzira. Icho chigadzirwa chakanakisa chekuchengetedza zvakatipoteredza uye ndechejira gobvu risiri rakarukwa.

Musiyano uripo pakati pepolypropylene uye polyester fibers

1、Kugadzira musimboti

Nheyo dzekugadzira dze polypropylene uye polyester fibers dzakasiyana. Polypropylene inogadzirwa nekupisa propylene monomers kune yakanyanya tembiricha uye nekuvawedzera kune catalyst yekupolymerization, nepo polyester fiber inogadziriswa kuita fiber zvinhu nekuwedzera cellulose etherification agents uye zvinonyungudutsa kune polyester resin.

2, Property maitiro

1. Panyaya yezvimiro zvemuviri:

Polypropylene ine huremu huremu uye ine yakakwira faibha simba, asi kupfeka kwayo kuramba uye tembiricha inodzivirira haina kunaka. Polyester fibers ane simba rakanyanya kusimba uye kusimba, pamwe nekupisa nemakemikari kuramba, zvichikonzera hupenyu hwesevhisi.

2. Panyaya yemakemikari zvinhu:

Polypropylene ine zvinhu zvakagadzikana zvemakemikari, haisi nyore kusvibiswa nemaasidhi, alkalis, nezvimwewo, uye haina zvinhu zvine chepfu uye zvinokuvadza. Polyester fiber ine benzene ring dhizaini uye ine imwe dhigirii rekusagadzikana.

3. Panyaya yehushamwari hwezvakatipoteredza:

Polypropylene ndeye thermoplastic zvinhu izvo zvisingaite biodegradable uye zvinosvibisa nharaunda. Polyester fibers inogona kuderedzwa nema microorganisms uye haizokonzeri kusvibiswa kune zvakatipoteredza.

Musiyano pakati pePP isiri-yakarukwa jira uyePET isina-yakarukwa jira

1. PP mbishi zvinhu zvakachipa, nepo PET zvigadzirwa zvinodhura. PP tsvina inogona kudzokororwa muchoto, nepo PET tsvina haigone kudzokororwa, saka mutengo wePP wakadzikira zvishoma.

2. PP ine tembiricha inodzivirira yeanenge 200 madhigirii, nepo PET ine tembiricha yekudzivirira inosvika 290 madhigirii. PET inoshingirira kutonhora kwakanyanya kupfuura PP.

3. Kudhinda kwemachira asina kuruka, kupisa kwekushisa, hupamhi hwakafanana PP inoderera zvakanyanya, PET inoderera zvishoma, ine mhedzisiro iri nani, PET inochengetedza yakawanda uye inorasa zvishoma.

4. Kubata simba, tension, kutakura mutoro, uye uremu hwakafanana, PET ine simba guru rekugadzirisa, kushushikana, uye kutakura mutoro kupfuura PP. 65 magiramu ePET akaenzana ne80 magiramu ePP maererano nekunetsekana, kushushikana, uye kutakura mutoro.

5. Kubva pakuona kwezvakatipoteredza, PP inosanganiswa nemarara ePP akadzokororwa, uye zvose PET chips itsva. PET ine hushamwari uye hutsanana kupfuura PP.
