Cov txiaj ntsig ntawm cov yas stacking crates yog dab tsi?

Cov thawv yas uas muab tso rau hauv (tseem hu ua cov thawv yas uas muab tso rau hauv lossis cov pob tawb yas uas muab tso rau hauv) feem ntau yog ua los ntawm polyethylene (PE) thiab polypropylene (PP). Lawv cov qauv tsim zoo heev thiab cov khoom siv ua rau lawv siv dav hauv kev xa khoom, kev tswj hwm tsev rau khoom, thiab kev khaws cia txhua hnub. Lawv yog cov cuab yeej tseem ceeb rau kev txhim kho kev siv qhov chaw thiab kev ua haujlwm zoo hauv cov saw hlau niaj hnub thiab kev khaws cia txhua hnub.

Cov txiaj ntsig tseem ceeb
1. Sib dua thiab yooj yim nqa:Vim lawv cov khoom siv tsawg (PE/PP qhov ceev yog kwv yees li 0.9-0.92g/cm³), lawv tsuas hnyav li 1/5-1/3 ntawm cov pob zeb lossis cov ntoo loj tib yam. Txawm tias muaj cov khoom puv nkaus (xws li khaub ncaws lossis cov cuab yeej), ib tus neeg tuaj yeem nqa lawv tau yooj yim. Qee cov qauv kuj muaj cov tes tuav sab lossis cov tes tuav nkhaus rau kev tuav zoo dua thiab txo qhov nkees ntawm kev tuav.

2. Kev Ruaj Khov thiab Kev Ruaj Khov Zoo Tshaj Plaws:
* Kev Cuam Tshuam:Cov khoom siv PE/PP muaj kev ruaj khov zoo heev, tiv taus kev tawg ntawm qhov kub qis (-20°C txog -30°C) thiab kev hloov pauv ntawm qhov kub siab (60°C-80°C, nrog rau qee cov qauv tiv taus cua sov uas muaj peev xwm tshaj 100°C). Nws tiv taus kev sib tsoo thiab kev poob txhua hnub (los ntawm qhov siab ntawm 1-2 meters) nrog lub neej ntev dua li daim ntawv cardboard (siv dua ntau dua 50 zaug, txawm tias ntau xyoo).
* Kev Tiv Thaiv Kev Xeb:Tsis nqus dej thiab tsis xeb, tiv taus cov kua qaub, alkalis, roj, thiab cov tshuaj yaj (xws li cov tshuaj ntxuav thiab cov tshuaj tua kab). Nws yuav tsis pwm, lwj, lossis xeb thaum kov cov khoom ntub (xws li cov khoom tshiab thiab cawv) lossis cov khoom siv raw hauv kev lag luam (xws li cov khoom siv kho vajtse thiab cov yas pellets).

3. Kev Siv Qhov Chaw Thiab Kev Siv Qhov Chaw Zoo:
* Kev tsim qauv stacking txheem:Lub hauv qab ntawm lub thawv thiab lub hau (lossis qhov qhib rau cov qauv tsis muaj hau) sib phim zoo, ua rau cov thawv khoob tuaj yeem "zes" (txuag tau ntau dua 70% qhov chaw) thiab cov thawv puv tuaj yeem "stacking ruaj khov" (feem ntau yog 3-5 txheej, nrog lub peev xwm thauj khoom ntawm 50-100kg ib txheej, nyob ntawm tus qauv), tiv thaiv kev ntxeev. Tus qauv tsim no yog qhov tsim nyog tshwj xeeb rau kev sib sau ua ke hauv cov tsev rau khoom thiab rau kev thauj khoom thauj khoom.
* Xaiv cov qauv uas muaj "stacking stoppers":Cov no ntxiv kom ruaj ntseg cov thawv uas tau teeb tsa ua ke kom tiv thaiv kev txav mus los thiab pab txhawb kev co (xws li kev thauj mus los ntawm tsheb thauj khoom).

4. Kev Hloov Pauv Tau Ntau Yam:
* Cov qauv yooj ywm:Muaj cov qauv uas muaj lossis tsis muaj lub hau, nrog lossis tsis muaj cov khoom faib, thiab nrog lub log lossis cov qauv ruaj khov. Xaiv koj qhov kev teeb tsa xav tau (piv txwv li, lub hau tiv thaiv cov hmoov av thiab cov dej noo, cov khoom faib teeb tsa cov khoom me me, thiab lub log pab txhawb kev txav mus los ntawm cov khoom hnyav).
*Kho tau raws li koj xav tau:Txhawb kev luam ntawv logo, kev hloov xim (feem ntau muaj xim dub, dawb, xiav, thiab liab), qhov cua (haum rau cov khoom tshiab thiab cov nroj tsuag), thiab xauv (haum rau cov khoom muaj nqis), ua tau raws li kev xav tau kev lag luam lossis kev lag luam.

5. Zoo rau ib puag ncig thiab pheej yig:
* Cov Khoom Siv Zoo Rau Ib Puag Ncig:Ua los ntawm cov khoom noj khoom haus PE/PP, tsim nyog rau kev sib cuag nrog zaub mov (xws li txiv hmab txiv ntoo, zaub, thiab khoom noj txom ncauj), thiab ua raws li FDA thiab GB 4806 cov qauv kev nyab xeeb, cov thawv no tsis muaj ntxhiab thiab tsis tso cov tshuaj lom.
* Rov siv tau dua:Cov thawv pov tseg tuaj yeem raug rhuav tshem thiab rov ua dua tshiab rau kev siv dua tshiab, ua rau lawv zoo rau ib puag ncig thiab zoo rau ib puag ncig dua li cov thawv ntawv pov tseg.
*Tus nqi tsim nyog:Tus nqi ntawm cov khoom feem ntau yog li ntawm 10-50 yuan (me mus rau nruab nrab), thiab lawv tuaj yeem siv dua tau ntau xyoo, nrog rau tus nqi mus sij hawm ntev qis dua li cov thawv ntawv (uas xav tau hloov pauv ntau zaus) lossis cov thawv ntoo (uas yooj yim puas tsuaj thiab kim).
* Yooj yim rau kev ntxuav thiab tswj:Qhov chaw du thiab tshem tawm cov ces kaum tuag thiab tuaj yeem ntxuav nrog dej, daim ntaub, lossis lub tshuab dej siab (haum rau cov chaw muaj roj hauv kev lag luam). Nws tiv taus cov xim av thiab cov kab mob, ua rau nws tsim nyog rau cov ntawv thov uas xav tau cov qauv kev huv huv siab, xws li zaub mov thiab kev kho mob.
