Nekuda kwezvikonzero zvakasiyana-siyana, cheni yeindasitiri yemakemikari yakakwira zvakanyanya, uye mitengo yemazhinji ezvigadzirwa zvemakemikari yakakwira.Indasitiri yezvigadzirwa zvehutsanana ichiri kutambura gore rino uye iri kukanganiswa zvakananga.
Vazhinji vatengesi vezvinhu zvakasvibirira uye zvekubatsira (kusanganisira mapolymers, spandex, machira asiri akarukwa, nezvimwewo) muindasitiri yehutsanana vakazivisa kuwedzera kwemutengo.Chikonzero chikuru chekuwedzera kushaikwa kwezvinhu zvinokwira kumusoro kana kuwedzera kunoramba kuchikwira kwemitengo.Vamwe vakatoti vasati vaisa order Inoda kutaurirana zvakare.
Vanhu vazhinji vakafungidzira: Mitengo yekumusoro yakakwira, iyo mutengo wekuwedzera tsamba kubva kumugadziri wechigadzirwa chakapedzwa ichave kumashure here?
Pane chokwadi chekufungidzira uku.Funga nezve magadzirirwo uye zvigadzirwa zvemanapukeni, napkins dzehutsanana, uye mapepi akanyorova.
Wet wipes anonyanya kuve machira asiri akarukwa, ukuwo manapukeni nemanapukeni ehutsanana anowanzo aine zvinhu zvikuru zvitatu: pamusoro pedhiri, inonyudza layer, uye yepasi layer.Aya mahombe maumbirwo anosanganisira mamwe makemikari mbishi zvinhu.
1. pamusoro layer: asiri akarukwa jira mutengo kuwedzera
Mucheka usina-wakarukwa hausi chete pamusoro pezvinhu zvemadiapers uye sanitary napkins, asiwo chinhu chikuru chemvura inopukuta.Machira asiri akarukwa anoshandiswa muzvigadzirwa zvehutsanana zvinoraswa anogadzirwa nemakemikari fibers anosanganisira polyester, polyamide, polytetrafluoroethylene, polypropylene, kabhoni faibha, uye girazi faibha.Zvinonzi zvinhu izvi zvemakemikari zviri kukwirawo mumutengo, saka mutengo wemachira asina kurukwa uchakwira nekumusoro kwayo, uye nekuda kwechikonzero chimwe chete, zvigadzirwa zvakapedzwa zvezvigadzirwa zvehutsanana zvinozokwira zvakare.
2. Absorbing layer: mutengo wezvinhu zvinotora SAP inowedzera
SAP ndiyo yakanyanya kuumbwa kweiyo inonyudza layer yemanapukeni uye sanitary napkins.Macromolecular water-absorbing resin ipolymer ine mvura-inosveta zvinhu iyo inogadzirwa ne hydrophilic monomers.Iyo yakajairika uye yakachipa yakadaro monomer ndeye acrylic acid, uye iyo propylene inotorwa kubva pakuputika kwepetroleum.Mutengo wepetroleum wakakwira, uye mutengo we acrylic acid Kutevera kukwira, SAP ichasimuka.
3. Mutsara wepasi: kuwedzera kwemutengo we polyethylene yakasvibiswa
Iyo yepasi pasi yemanapukeni uye sanitary napkins ifirimu inoumbwa, iyo inoumbwa neinofema pasi firimu uye jira risiri rakarukwa.Inoshumwa kuti iyo inofema pasi firimu ifirimu yepurasitiki inogadzirwa kubva ku polyethylene.(PE, imwe yemhando huru dzepurasitiki, inogadzirwa kubva ku polyethylene Polymer zvinhu.) Uye ethylene, sechinhu chinowanzoshandiswa petrochemical chigadzirwa, inonyanya kushandiswa kugadzira plastiki raw material polyethylene.Mafuta asina kuchena ari kuratidza kukwira kumusoro, uye mutengo wemembrane inofema uchishandisa polyethylene seyakagadzirwa inogona kukwira sezvo mutengo wepolyethylene uchikwira.
Kukwira kwemutengo wezvinhu zvakasvibirira kuchaisa kumanikidza pamutengo wevakapedzwa vanogadzira zvigadzirwa.Pasi pekumanikidzwa uku, hapana chinopfuura mhedzisiro miviri:
Imwe ndeyekuti vagadziri vezvigadzirwa vakapedzwa vanoderedza kutengwa kwezvinhu zvakasvibirira kuti vaderedze kudzvanywa, izvo zvinoderedza kugona kwekugadzira diapers;
Imwe yacho ndeyekuti vagadziri vezvigadzirwa vakapedza vanogovana kudzvanywa kune vamiririri, vatengesi uye vatengi.
Chero mamiriro ose ezvinhu, kuwedzera kwemutengo pamagumo ekutengesa kunoratidzika kusingadzivisiki.
Zvechokwadi, zviri pamusoro apa ingori fungidziro.Vamwe vanhu vanofunga kuti kuwedzera kwemutengo uku hakuna kugadzikana, uye iyo terminal ichine hesiti yekutsigira, uye kuwedzera kwemutengo kwezvakapera zvigadzirwa kungasauya.Parizvino, hapana vagadziri vezvigadzirwa vakapedza vakapa zviziviso zvekuwedzera kwemutengo.
