Breathble pla spunbond nonwoven

Parizvino, polypropylene (PP) ichiri chinhu chikuru chinoshandiswa mumachira asiri akarukwa, uye zvimiro zvayo zvekuora hazvizadzise zvinodiwa zvekuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba. Kukurudzira kushandiswa kwezvigadzirwa zvebiodegradable mumunda wemachira asina kurukwa ndiwo uchava maitiro. Machira akasiyana-siyana asina kurukwa akagadzirwa kubva kupolylactic asidhi anogona kuparara, uye mamwe anosanganisa polylactic asidhi nemamwe mafiibhi echisikigo kana mafiibhi ekugadzira kuti chigadzirwa chekupedzisira chive chiorere.

Polylactic asidhi (PLA) rudzi rutsva rwezvinhu zvinoora zvinogadzirwa kubva kune starch inotorwa kubva kune zvinogonekazve chirimwa zviwanikwa zvakaita sechibage. Starch mbishi zvinhu zvinoiswa saccharified kuti iwane glucose, iyo inozoviriswa nemamwe madhiri kuburitsa yakakwira-kuchena lactic acid. Zvadaro, imwe molecular huremu hwepolylactic acid inogadzirwa kuburikidza nemakemikari synthesis nzira. Iine biodegradability yakanaka uye inogona kuderedzwa zvachose nehutachiona muzvisikwa mushure mekushandiswa, pakupedzisira ichigadzira kabhoni dhaidhiyo uye mvura pasina kusvibisa nharaunda.

Izvi zvinobatsira kwazvo kuchengetedza zvakatipoteredza uye zvinozivikanwa sechinhu chinochengetedza zvakatipoteredza. Kutarisira Pasi, tine mutoro. Maererano nemishumo yenhau, kubudiswa kwecarbon dioxide pasi rose kunotarisirwa kukwira kusvika pa60 ℃ panosvika 2030. Nzira yokurapa nayo mapurasitiki akajairika ichiri kupiswa uye kupiswa, zvichiita kuti magasi akawanda egreenhouse abudiswe mumhepo. Polylactic acid mapurasitiki, kune rumwe rutivi, anovigwa muvhu nokuda kwekuora, kubudisa carbon dioxide iyo inopinda zvakananga muvhu organic matter kana inotorwa nemiti, isina kubudiswa mumhepo kana kukonzera greenhouse effect.

Hunhu hwePLA polylactic acid isiri-yakarukwa jira

Hunyoro hunoratidza, hunofema, hunochinjika, huremu, husingabatike, huri nyore kuora, husina chepfu uye husingatsamwisi, hune ruvara rwakapfuma, hunogona kushandiswa zvakare.

Muenzaniso wekushandisa wePLA isiri-yakarukwa jira

Tichitora machira asiri akarukwa mundima dzekurapa uye dzehutano semuenzaniso, PLA machira asiri akarukwa haangozadzise zvakakwana kuchengetedzwa uye kushandiswa zvinodiwa zvemidziyo yekudzivirira inoraswa, asiwo inopa chigadzirwa nehutsva hwakasvibira uye hushamwari hwezvakatipoteredza. Mushure mekushandiswa, inogona kuve yakasvibiswa zvachose pasi pemamiriro ekugadzira manyowa mukati memwedzi mishomanana, kwete chete pasina kukonzera chero mutoro kune zvakatipoteredza, asiwo kutora chikamu mukutenderera kwechisikigo.

Uye zvakare, polylactic acid membrane jira chinhu chitsva chebiological based material ine ruoko rwakapfava kunzwa, yakasimba adsorption, kuchengetedza mwando, kufema uye bacteriostasis. Iyo yakachena, yakachengeteka, ine hutano uye iri padyo neganda remhando yepamusoro zvinhu. Iyo ine akawanda biological maitiro ayo mamwe ma substrates haakwanise kuenderana, uye yakanakira substrate yemasiki emhando yepamusoro kumeso.
