Amakhreyithi okupakisha epulasitiki (abuye aziwe ngokuthi amakhreyithi entengo yepulasitiki noma obhasikidi abanqwabelene bepulasitiki) enziwa ngokuyinhloko nge-polyethylene (PE) ne-polypropylene (PP). Idizayini yabo ephakeme kakhulu yesakhiwo kanye nezakhiwo zezinto ezibonakalayo zibenza basetshenziswe kabanzi ekuphatheni impahla, ekuphathweni kwempahla, nasekugcinweni kwansuku zonke. Ziyithuluzi elibalulekile lokuthuthukisa ukusetshenziswa kwendawo kanye nokwenza kahle ukusebenza kahle kumaketanga okuhlinzeka ngempahla yesimanje kanye nokugcinwa kwansuku zonke.
Izinzuzo Eziyinhloko
1. Ingasindi futhi Kulula Ukuyithwala:Ngokuminyana kwazo okuphansi (ukuminyana kwe-PE/PP cishe ku-0.9-0.92g/cm³), zinesisindo esingu-1/5-1/3 kuphela sikakhonkolo noma amakhreyithi okhuni anosayizi ofanayo. Ngisho zigcwele ngokugcwele izinto (njengezingubo noma amathuluzi), zingathwalwa kalula ngumuntu oyedwa. Ezinye izitayela nazo zifaka izibambo eziseceleni noma izibambo zokuthwala ezigobile zokunethezeka okuthuthukisiwe nokubamba nokukhathala okuncishisiwe kokusingatha.
2. Ukuqina Nokuqina:
*Ukumelana Nomthelela:Izinto ze-PE/PP zinikeza ukuqina okuhle kakhulu, zimelana nokuqhekeka emazingeni okushisa aphansi (-20°C kuya ku-30°C) kanye nokonakala emazingeni okushisa aphezulu (60°C-80°C, namanye amamodeli amelana nokushisa akwazi ukweqa u-100°C). Imelana nokungqubuzana nokuwa kwansuku zonke (kusuka endaweni ephakeme ngamamitha angu-1-2) nempilo edlula kude le yekhadibhodi (ingasetshenziswa kabusha izikhathi ezingaphezu kuka-50, ngisho neminyaka).
*Ukumelana nokugqwala:Ayimunzi amanzi futhi imelana nokugqwala, imelana nama-asidi, ama-alkali, uwoyela, nezincibilikisi zamakhemikhali (njengezinto zokuhlanza ezivamile nezihlanjululi zezibulala-zinambuzane). Ngeke ibumbe, ibole, noma igqwale lapho ithintana nezinto ezimanzi (njengomkhiqizo omusha notshwala) noma izinto zokusetshenziswa zasembonini (njengezingxenye zehardware namapellets epulasitiki).
3. Ukupakishwa Okuphumelelayo Nokusetshenziswa Kwesikhala:
* Umklamo wokupakisha ojwayelekile:Ibhokisi eliphansi nesivalo (noma ukuvula amamodeli angenazivalo) kufanelana ngokuqondile, okuvumela amabhokisi angenalutho ukuba "abekwe" (konga isikhala esingaphezu kuka-70%) futhi amabhokisi agcwele "abekwe ngokuhlelekile" (ngokujwayelekile izendlalelo ezingu-3-5, ezinomthamo womthwalo we-50-100kg ungqimba ngalunye, kuye ngokuthi imodeli), ukuvimbela ukugoqa. Lo mklamo ulungele ikakhulukazi ukupakishwa okuminyene ezindaweni zokugcina izimpahla kanye nezokuthutha ngamaloli.
* Khetha amamodeli afaka "izivimba zokupakisha":Lokhu kuphinde kuvikeleke amabhokisi astakiwe ukuze kuvinjwe ukugudluka futhi kuvumele ukundindizela (njengokuthutha ngamaloli).
4. Ukuzivumelanisa nezimo:
* Isakhiwo esivumelana nezimo:Itholakala ngamamodeli anezivalo noma angenazo, anezihlukanisi noma ezingenazo, futhi anamasondo noma ukulungiselelwa okungashintshi. Khetha ukumisa okufunayo (isb., izivalo zivikela uthuli nomswakama, abahlukanisi bahlela izingxenye ezincane, namasondo asiza ukunyakaza kwezinto ezinzima).
*Kungenziwa ngendlela oyifisayo:Isekela ukuphrinta kwelogo, ukushintsha kombala (okuvame ukutholakala ngokumnyama, okumhlophe, okuluhlaza okwesibhakabhaka, nokubomvu), izimbobo zokungenisa umoya (ezifanele umkhiqizo omusha nezitshalo), nezingidi (ezifanele izinto ezibalulekile), ukuhlangabezana nezidingo zokwenza ngokwezifiso zezentengiso noma zezimboni.
5. Ivumelana Nemvelo Futhi Izindleko Eziphansi:
*Izisetshenziswa Ezilungele Imvelo:Enziwe nge-PE/PP yezinga lokudla, alungele ukuthintana nokudla (okufana nezithelo, imifino, nokudla okulula), futhi athobelana namazinga okuphepha e-FDA kanye ne-GB 4806, lawa mabhokisi awanuki futhi awakhiphi izinto eziyingozi.
*Ingaphinda isetshenziswe:Amabhokisi alahliwe angacutshungulwa futhi acutshungulwe kabusha ukuze agaywe kabusha, awenze alungele imvelo futhi avumelane nemvelo kunamakhadibhodi alahlwayo.
*Kuqiza kahle:Izintengo zamayunithi ngokuvamile zisukela kumayuan angu-10-50 (amancane kuya kosayizi ophakathi), futhi angasetshenziswa kabusha iminyaka, nezindleko zesikhathi eside eziphansi kakhulu kunamakhadibhodi (adinga ukushintshwa njalo) noma amabhokisi okhuni (alimala kalula futhi abizayo).
*Kulula Ukuhlanza Nokugcina:Indawo ebushelelezi iqeda amakhona afile futhi ingahlanzwa ngamanzi, i-rag, noma indiza yamanzi enomfutho ophezulu (efanele izindawo ezingcoliswe uwoyela wezimboni). Imelana namabala namabhaktheriya, iyenze ifaneleke ikakhulukazi izinhlelo zokusebenza ezidinga izindinganiso eziphakeme zokuhlanzeka, njengokudla nezokwelapha.
