Ukuhanjiswa ngokuchanekileyo kwiCuisine Processing

Kwishishini lecuba, iibhanti zokuhambisa azizo nje izinto zokuphatha izinto—zibalulekile ekugqibeleleni kwemveliso, kulawulo lomgangatho, nasekuthobeleni imithetho. Ukususela ekucutshungulweni kwamagqabi aluhlaza ukuya ekucutshungulweni kokuqala kunye nokuveliswa kwecuba eligqityiweyo, iimfuno kwiinkqubo zokuhambisa ziphezulu kakhulu: ukumelana nothuli, iimpawu ezichasene nokuma, uzinzo lweekhemikhali, kunye nokunamathela ngokungqongqo kwimigangatho yokhuseleko lokutya kunye ne-pyrolysis.

Kwiinjineli zezityalo, abaphathi bokuthenga, kunye nabadibanisi bezixhobo abavavanya izisombululo zokuhambisa, umbuzo ubalulekile: Yintoni eyenza i-Ibhanti yokuhambisa i-PEukhetho olukhethwayo kwizicelo zoshishino lwecuba, kwaye abathengi bafanele bajonge ntoni?

A Ibhanti yokuhambisa ye-PE (polyethylene)sisisombululo sebhanti esilula esakhiwe ngesakhelo selaphu le-polyester kunye nomaleko wokugquma we-polyethylene. Sinika ukumelana nokuguguleka okugqwesileyo, uzinzo lweekhemikhali, iipropati zokulwa nokunganyakazi, kunye nokuthobela imigangatho yokhuseleko lokutya ye-FDA—okuyenza ifaneleke ngokufanelekileyo kwiimfuno ezifunekayo zoshishino lwecuba.

Kutheni i-PE isetyenziselwa icuba? Ukuqonda iingenelo zezinto eziphathekayo

Ukwakhiwa kwezinto

I-PE (i-polyethylene) yi-polymer ye-thermoplastic eyaziwa ngesakhiwo sayo esilula se-molecular kunye nokusetyenziswa kwayo ngokubanzi. Kulwakhiwo lwebhanti yokuhambisa, i-PE idla ngokudityaniswa nomaleko wokuqinisa ilaphu le-polyester ukubonelela ngokuguquguquka kunye namandla okutsalwa.

Iimpawu zeMpahla eziPhambili

Imfuneko yePyrolysis

Uphawu olwahlukileyo lweebhanti zokuhambisa icuba kukwazi kwazo ukuphumelela uvavanyo lwe-pyrolysis—uhlalutyo lokutsha oluqinisekisa ukuba akukho kukhululwa kweekhompawundi ze-nitrogen okanye ze-halogenated. Ngokungafaniyo ne-PVC eyenziwe ngeplastiki, ii-polyolefins ezifana ne-PE ziyatsha ukuze zenze phantse i-carbon dioxide kunye nomphunga wamanzi kuphela, ngaphandle kweemveliso ezinobungozi. Oku kuthobela kuyimfuneko enyanzelekileyo kwizixhobo zoshishino lwecuba.

Iintlobo zeeBhanti zoThutho zePE zokusetyenziswa kwecuba

1. Iibhanti ze-PE eziGqibeleleyo

Ulwakhiwo oluqhelekileyo lokuhambisa icuba. Umphezulu ogudileyo, onganamatheliyo uqinisekisa ukukhululwa lula kwezinto zecuba ngelixa unciphisa ukunamathela kwemveliso. Ubukhulu obuqhelekileyo: 0.9mm–2.5mm.

Izicelo: Ukuphathwa kwamagqabi aluhlaza, imigca yokucubungula ephambili, ukuhanjiswa ngokubanzi.

2. Iibhanti zeConveyor ze-Oval Stud PE

Njengoko inepatheni ye-stud efana ne-oval kumphezulu, olu yilo lonyusa ukungqubana kunye nomthamo wokuthwala, luthintela ukutyibilika ngexesha lokuhambisa. Zenziwe ngezinto ze-HDPE, ezi bhanti zisebenza kakhulu ekuphatheni uthuli lwecuba kunye nobungakanani obahlukeneyo bemveliso.

Izicelo: Ukwahlulahlula, ukomisa, ukusika, kunye nokupakisha amacandelo.

3. Iibhanti ze-PE zeProfayili enqamlezileyo

Uyilo lweprofayili enqamlezileyo lwezicelo ezifuna ukubamba okongezelelweyo kunye nolawulo lwemveliso. Ubukhulu obuqhelekileyo: 5.0mm.

Izicelo: Ukuhambisa okuthambekileyo, ukuphakama kwemveliso.

4. Iibhanti ze-PE zePateni esezantsi

Umphezulu ongaphantsi onepateni yokuphucula ukubamba kwiirola zokuqhuba. Ubukhulu obuqhelekileyo: 5.0mm.

Iinkcukacha zobugcisa ngokwesicelo

Iiparameters eziphambili zokukhetha

1. Ukukhetha Ubukhulu

• 0.9mm – 1.2mm: Usetyenziso olulula, oluhambisa izinto ngokuthe tyaba
• 2.0mm – 3.0mm: Usetyenziso lomthwalo oluphakathi, oluphakathi
• 4.0mm – 5.0mm: Ii-applications ezisebenza nzima, ezineprofayili, iimfuno zozinzo oluphezulu

2. Ukufumaneka kobubanzi

Ububanzi obuqhelekileyo buhlala buqala kwi-300mm ukuya kwi-1000mm, kwaye ububanzi obulungiselelwe wena bufumaneka ukuya kuthi ga kwi-3000mm kuxhomekeke kumenzi.

3. Iiprofayili zomphezulu

4. Iimfuneko ezichasene nokuNgaguqukiyo

Uninzi lweebhanti ze-PE ezikumgangatho wecuba ziquka intambo eqhubayo kumaleko osezantsi ukuze kususwe itshaja engashukumiyo. Oku kubalulekile ekuthinteleni ukuqokelelwa kothuli nokuqinisekisa ukhuseleko lwabaqhubi kwiindawo ezinothuli.

Ubuchwepheshe obungenabungozi kwizinambuzane

Ingxaki ekhethekileyo yokwenziwa kwecuba kukungcoliswa kwecuba, okunokuphazamisa umgangatho wemveliso kunye nemigangatho yempilo. Iindlela zokwenziwa eziphambili zifaka ii-anti-mite agents (ezifana nee-isothiazolinone compounds) kwizinto ze-PE okanye unyango lwelaphu. Ezi arhente zithintela ukuveliswa kwecuba ngelixa zigcina ukuthotyelwa ngokupheleleyo kwemigaqo ye-FDA kunye ne-EU REACH. Le yeyona nto ibalulekileyo kubathengi abachaza ukubekwa kwecuba kwinqanaba lecuba.
