Isikhwama sokupakisha sePlastiki siwuhlobo lwesikhwama sokupakisha esisebenzisa ipulasitiki njengempahla eluhlaza futhi sisetshenziswa ekukhiqizeni imikhiqizo ehlukahlukene empilweni. Isetshenziswa kabanzi ekuphileni kwansuku zonke kanye nokukhiqizwa kwezimboni, kodwa ukukhululeka ngalesi sikhathi kuletha ukulimala kwesikhathi eside. Izikhwama zokupakisha zepulasitiki ezisetshenziswa kakhulu ngokuvamile zenziwe ngefilimu ye-polyethylene, engeyona enobuthi, ngakho-ke ingasetshenziswa ukuqukatha ukudla. Kukhona futhi ifilimu eyenziwe nge-polyvinyl chloride, yona ngokwayo engeyona enobuthi, kodwa izithasiselo ezengezwe ngokuvumelana nokusetshenziswa kwefilimu ngokuvamile ziyizinto eziyingozi futhi ezinobuthi obuthile. Ngakho-ke, amafilimu anjalo nezikhwama zepulasitiki ezenziwe amafilimu azifanelekile ukuqukatha ukudla.
Izikhwama zokupakisha zepulasitiki zingahlukaniswa zibeI-OPP, i-CPP, i-PP, i-PE, i-PVA, i-EVA, izikhwama eziyinhlanganisela, izikhwama ze-co-extrusion, njll.
| I-CPP | Okungeyona ubuthi, okuhlanganisiwe, obala okungcono kune-PE, ubulukhuni obubi kakhulu. Ukuthungwa kuthambile, ngokusobala kwe-PP kanye nokuthamba kwe-PE. |
| PP | Ukuqina kungaphansi kwe-OPP, futhi bunganwetshwa (ukunwebeka ngezindlela ezimbili) bese kudonselwa kunxantathu, uphawu olungezansi noma uphawu oluseceleni. |
| I-PE | Kukhona i-formalin, ebonisa ngale kancane |
| I-PVA | Ukuthungwa okuthambile, obala okuhle, kuwuhlobo olusha lwezinto zokuvikela imvelo, inyibilika emanzini, izinto ezingavuthiwe zingeniswa zivela eJapan, intengo iyabiza, futhi isetshenziswa kabanzi phesheya. |
| I-OPP | Ukucaca okuhle, ubulukhuni obuqinile |
| Isikhwama esiyinhlanganisela | Amandla okuvala aqinile, angaphrinteka, uyinki ngeke awe |
| Isikhwama esikhishwe ngokubambisana | Ukucaca okuhle, ukuthungwa okuthambile, okuphrintekayo |
Izikhwama zokupakisha zepulasitiki zingahlukaniswa zibe: izikhwama zepulasitiki ezilukiweyo nezikhwama zefilimu zepulasitiki ngokwezakhiwo ezihlukene zomkhiqizo kanye nokusetshenziswa
isikhwama esilukiwe
Izikhwama zepulasitiki ezilukiwe zakhiwa izikhwama ze-polypropylene nezikhwama ze-polyethylene ngokusho kwezinto eziyinhloko;
Ngokwendlela yokuthunga, ihlukaniswe yaba isikhwama esingaphansi komthungo kanye nesikhwama esingaphansi somthungo.
Impahla yokupakisha esetshenziswa kakhulu kumanyolo, imikhiqizo yamakhemikhali nezinye izinto. Inqubo yayo eyinhloko yokukhiqiza iwukusebenzisa izinto zokusetshenziswa zepulasitiki ukukhipha ifilimu, ukusika, nokunwebeka ngendlela engaqondile ibe yizintambo eziyisicaba, nokuthola imikhiqizo ngokusebenzisa i-warp and weft weaving, ngokuvamile okubizwa ngokuthi izikhwama ezilukiweyo.
Izici: isisindo esilula, amandla aphezulu, ukumelana nokugqwala, njll. Ngemva kokwengeza ifilimu yefilimu yepulasitiki, ingaba umswakama-ubufakazi kanye nomswakama-ubufakazi; umthamo womthwalo wezikhwama ezilula ungaphansi kuka-2.5kg, umthamo wezikhwama eziphakathi nendawo ungama-25-50kg, futhi umthamo wezikhwama ezinzima u-50-100kg
isikhwama sefilimu
Impahla eluhlaza yesikhwama sefilimu yepulasitiki i-polyethylene. Izikhwama zepulasitiki zilethe ngempela ukuphila kwethu kalula, kodwa ukuba lula ngalesi sikhathi kulethe ukulimala kwesikhathi eside.
Ihlukaniswa ngezinto ezingavuthiwe: izikhwama zepulasitiki ze-polyethylene ezinengcindezi ephezulu, izikhwama zepulasitiki ze-polyethylene ezinengcindezi ephansi, izikhwama zepulasitiki ze-polypropylene, izikhwama zepulasitiki ze-polyvinyl chloride, njll.
Ukuhlukaniswa ngokuma: isikhwama se-vest, isikhwama esiqondile. Izikhwama ezivaliwe, izikhwama zepulasitiki, izikhwama ezimise okukhethekile, njll.
Izici: izikhwama ezilula ezinomthwalo ongaphezu kwe-1kg; izikhwama eziphakathi nomthwalo we-1-10kg; izikhwama ezinzima ezinomthwalo we-10-30kg; izikhwama zeziqukathi ezinomthwalo ongaphezu kuka-1000kg.
Izikhwama zepulasitiki zokudla zivame ukusetshenziswa ezimpilweni zabantu, kodwa kufanele uqaphele lapho uzisebenzisa. Ezinye izikhwama zepulasitiki zinobuthi futhi azikwazi ukusetshenziselwa ukugcina ukudla ngokuqondile.
1. Ukubuka ngamehlo
Izikhwama zepulasitiki ezingezona ezinobuthi zimhlophe, zisobala noma zibonakala kancane, futhi zinokuthungwa okufanayo; Izikhwama zepulasitiki ezinobuthi zinemibala noma zimhlophe, kodwa azibonakali kahle futhi zinemfucumfucu, futhi indawo yepulasitiki yeluliwe ngokulinganayo futhi inezinhlayiya ezincane.
2. Lalela ngezindlebe zakho
Lapho isikhwama sepulasitiki sinyakaziswa ngamandla ngesandla, umsindo ohlabayo ubonisa ukuthi isikhwama sepulasitiki esingenabuthi; futhi umsindo omncane futhi ongacacile uyisikhwama sepulasitiki esinobuthi.
3. Thinta ngesandla
Thinta ubuso besikhwama sokupakisha sepulasitiki ngesandla sakho, bushelelezi kakhulu futhi asinabuthi; okunamathelayo, okuhlabayo, umuzwa we-waxy unobuthi.
4. Ukuhogela ngamakhala akho
Izikhwama zepulasitiki ezingenabuthi azinaphunga; lezo ezinephunga elimnandi noma ukunambitheka okungavamile zinobuthi.
5. Indlela yokuhlola ukucwiliswa emanzini
Faka isikhwama sepulasitiki emanzini, usicindezele phansi emanzini ngesandla sakho, ulinde isikhashana, isikhwama sepulasitiki esingenabuthi esavela isikhwama sokupakisha sepulasitiki esingenabuthi, kanye naso esicwila emanzini. ngezansi kunesikhwama sokupakisha sepulasitiki esinobuthi.
6. Indlela yomlilo
Izikhwama zepulasitiki ezingenabuthi ziyavutha, isihloko selangabi siphuzi, futhi isihloko selangabi siluhlaza. , phansi kuluhlaza, ukuthambisa kungaxutshwa, futhi uzwa iphunga elimnandi
