Kutakura Fodya Nemazvo

Muindasitiri yefodya, mabhendi ekufambisa zvinhu haasi ekubata zvinhu chete—akakosha pakuvimbika kwechigadzirwa, kudzora mhando, uye kutevedzera mitemo. Kubva pakugadzira mashizha matema kusvika pakugadzira fodya yekutanga uye kugadzirwa kwefodya yakapedzwa, zvinodiwa pamasisitimu ekufambisa zvinhu zvakanyanya: kuramba guruva, hunhu hwekudzivirira kusimba kwemakemikari, kugadzikana kwemakemikari, uye kutevedzera mitemo yekuchengetedza chikafu uye pyrolysis.

Kune mainjiniya emiti, vatariri vekutenga, uye vanobatanidza michina vari kuongorora mhinduro dzekutumira, mubvunzo unokosha: Chii chinoita kuti pave nebhandi rekutakura zvinhu rePEsarudzo inonyanya kufarirwa yekushandiswa muindasitiri yefodya, uye vatengi vanofanira kutsvagei?

A bhandi rekutakura zvinhu rePE (polyethylene)mushonga webhandi wakareruka wakagadzirwa nepurasitiki yakagadzirwa nejira uye polyester coating layer. Inodzivirira kupfekwa zvakanaka, kugadzikana kwemakemikari, hunhu hunodzivirira kusamira kwemvura, uye kutevedzera mitemo yeFDA yekuchengetedza chikafu—zvichiita kuti ive yakakodzera zvinodiwa neindasitiri yefodya.

Sei PE ichifanira kushandiswa nefodya? Kunzwisisa Kubatsira kweFodya

Kuumbwa Kwezvinhu

PE (polyethylene) ipolymer inogadzirwa nethermoplastic inozivikanwa nekuumbwa kwayo kuri nyore kwemamorekuru uye kushanda kwayo kwakafara. Mukugadzira bhandi rekutakura zvinhu, PE inowanzo sanganiswa nejira rekusimbisa jira repolyester kuti ipe kuchinjika uye simba rekusunga.

Zvimiro Zvinokosha zveZvinhu

Chinodiwa chePyrolysis

Chinhu chinosiyanisa mabhendi emhando yefodya ndiko kugona kwawo kupasa bvunzo yepyrolysis—ongororo yekupisa iyo inoita kuti pasave nekuburitswa kwemakemikari ane nitrogen kana halogenated. Kusiyana nePVC yakagadzirwa nepurasitiki, mapolyolefins akaita sePE anotsva kuti agadzire kabhoni dioxide neutsi hwemvura chete, pasina zvinhu zvine njodzi. Kutevedzera uku chinodiwa chemidziyo yefodya.

Mhando dzeMabhande ePe Conveyor ekushandisa Fodya

1. Mabhandi ePE Akapfava Pamusoro

Magadzirirwo akajairwa ekutakura fodya. Nzvimbo yakatsetseka, isinganamatire inoita kuti fodya iburitswe zviri nyore uku ichideredza kunamira kwechigadzirwa. Ukobvu hwakajairika: 0.9mm–2.5mm.

Mashandisirwo: Kubata mashizha egirini, mitsetse yekutanga yekugadzirisa, kutakura kwakajairika.

2. Mabhandi eOval Stud PE Conveyor

Nechimiro che stud chakaita sedenderedzwa pamusoro, dhizaini iyi inowedzera kukweshana uye kugona kutakura, ichidzivirira kutsvedza panguva yekutakura. Yakagadzirwa nezvinhu zveHDPE, mabhandi aya anonyanya kushanda pakubata guruva refodya uye saizi dzakasiyana dzechigadzirwa.

Mashandisirwo: Kuronga, kuomesa, kucheka, uye kurongedza zvikamu.

3. Mabhandi ePE ane muchinjikwa

Dhizaini yeprofile yakachinjika yemashandisirwo anoda kubatwa kwakawedzerwa uye kudzorwa kwechigadzirwa. Ukobvu hwakajairika: 5.0mm.

Mashandisirwo: Kutakura kwakapfava, kukwidziridzwa kwechigadzirwa.

4. Mabhandi ePE ePattern yepazasi

Nzvimbo yepasi yakagadzirwa nemapatani ekuvandudza kubata pamaroller ekutyaira. Ukobvu hwakajairika: 5.0mm.

Magadzirirwo ehunyanzvi nekushandisa

MaParamende Akakosha Ekusarudza

1. Sarudzo yeKukora

• 0.9mm - 1.2mm: Zvishandiso zvisina basa, kutakura kwakatsetseka
• 2.0mm - 3.0mm: Kushandiswa kwemutoro uri pakati nepakati, uri pakati nepakati
• 4.0mm - 5.0mm: Mashandisirwo anorema, akaumbwa neprofile, zvinodiwa pakugadzikana kwakanyanya

2. Kuwanikwa kweUpamhi

Upamhi hwakajairika hunowanzova pakati pe300mm kusvika 1000mm, uye upamhi hwakagadziriswa hunowanikwa hunosvika 3000mm zvichienderana nemugadziri.

3. Mapurofayiri Epamusoro

4. Zvinodiwa Zvinopesana Nekusagadzikana

Mabhandi mazhinji ePE emhando yefodya anoshandisa shinda inofambisa mhepo pasi kuti ibvise simba rayo. Izvi zvakakosha pakudzivirira kuungana kweguruva uye kuona kuchengetedzeka kwemushandisi munzvimbo dzine guruva.

Tekinoroji Inodzivirira Zvipembenene

Chinhu chinonyanya kukosha pakugadzira fodya ndechekusvibiswa kwezvipenyu, izvo zvinogona kukanganisa kunaka kwezvigadzirwa uye mwero wehutano. Nzira dzekugadzira dzepamusoro dzinosanganisira mishonga inorwisa zvipenyu (senge isothiazolinone compounds) muPE zvinhu kana jira. Mishonga iyi inodzivirira kubereka kwezvipenyu uku ichiramba ichitevedzera zvizere mitemo yeFDA neEU REACH. Iyi inyaya huru yekufunga nezvayo kune vatengi vanotsanangura bhandi remhando yefodya.
