Intetho yeplastiki malunga nomahluko phakathi kokubetha kunye nenaliti yokubumba

September 04, 2023

Ukuvuthuza ukubumba, okwabizwa ngokuba njengokutsala kwe-hills, kukuphuhlisa ukuqhubekeka ngokukhawuleza kweplastiki. Inkqubo yokuvuthuza yaqala ukuvelisa uxinaniso ophantsi kwe-Polythylene kwiMfazwe yesibini yeHlabathi. Ngasekupheleni kweminyaka yee-1950, ngokuzalwa kwe-pollithylene ephezulu kunye nokuphuhliswa koomatshini bokuvuthuza, itekhnoloji yokubetha isetyenziswe ngokubanzi. Inaliti yokubumba yindlela yokuvelisa imilo yemveliso yomizi-mveliso. Iimveliso zihlala zinenaliti ebunjiweyo kwirabha kunye neplastiki. Oku kulandelayo luthotho oluncinci lwe-jiuzhi.com ukukuxelela malunga nomahluko phakathi kwendlela yokubetha kunye nenaliti. Kukho amanqaku amathathu aphambili:

1. Inkqubo yahlukile, ukubetha ukubumba kuyinto yokuqhozula +. Inaliti yokubumba inambatho + uxinzelelo; Ukurhafiswa kokujikeleziswa kukuphelelwa + koxinzelelo; I-vessong ye-flound kufuneka iphumelele intloko eshiyekileyo ngokunyusa umbhobho wegesi, kwaye inaliti yesisu kufuneka ibe necandelo leSango. I-rotomolding kufuneka inqunywe ngaphandle kokuqhwaba.

2. Ngokubanzi, inaliti yokubumba sisiseko esiqinileyo, kwaye ukubetha ubumba kunye ne-rotomolds yi-Cores. Umphezulu wamava abunjiweyo aqaqambile, kwaye umphezulu wokuxhuzulwa kukubumba, kwaye irobhothi ayilingani. Ukubetha ukubumba kunye ne-rotomold kukwisiphatho esincinci. Kukho umlomo ovuthuzayo. Olu thelekiso ngokubanzi.

3. Iplastiki yeplastiki kunye nefuthe lezinto ezichaphazela iimpawu ze-thermoverics ukuba ziyanda emva kokufudumeza, zincipha emva kokupholisa, kwaye ngokuqinisekileyo iya kuncipha emva koxinzelelo. Kwinkqubo yokuxhuzula inaliti, iplastiki etyhidiweyo iqale igcinwe kwi-sold cavity, kwaye emva kokugcwaliswa kuyaphoswa, inyibilikisiwe kwaye iqinile, kwaye i-shrinkage ikhutshiwe xa kubizwa njalo ukwenza i-shrinkage. Ubungakanani benxalenye yeplastiki busaya kutshintsha kancinci ukusuka kwixesha lokubumba kuyasuswa kwimeko yokuhlala. Utshintsho olunye kukuqhubeka nokuncipha. Le shrinkage ibizwa ngokuba yi-Shrinkage. Omnye umahluko kukuba ezinye iiplanga ze-hygroscopic zifikile ngenxa yokufumana umswakama. Umzekelo, xa umxholo wamanzi we-NYLOLO 610 yi-3%, ukunyuka okukhulu yi-2%; Kwaye xa umxholo wamanzi we-fiber fiber firicint-nylon 66 ngama-40%, unyuso lwe-0.3%. Kodwa eyona ndima iphambili kukwenza i-shrinkage.
