Mochini oa ho etsa li-blouse ke eng?
Mochini oa ho etsa blow o fetola resin ea polasetiki hore e be likarolo tse sekoti ka ho e qhibilihisa, ho e etsa sebopeho se bonolo, le ho bululela moea o hatelletsoeng ka har'a sebopeho seo e le hore o hatelle hlobo. Ha polasetiki e pholile 'me hlobo e buleha, u na le sehlahisoa se felileng se se nang letho - botlolo, sekoti, moqomo, tanka. Hoo e batlang e le sejana se seng le se seng se thata sa polasetiki seo u se tšoarang se qalile ka mochini oa ho bopa oa mofuta o mong kapa o mong.
Sehlopha se pharaletse hobane likarolo li fapane haholo: 100 ml eyedropper bottle le 220 L chemical drum ka bobeli ke "blow molded," empa ha ho letho ka mechini ena e 'meli le ts'oanang. Ho khetha hantle ho bolela ho utloisisa lintho tse peli - hore na sebopeho se bonolo se entsoe joang (themofuta oa ts'ebetso), le hore na mochini o hahiloe joang ho o tsamaisa (thesebopeho).

Sephetho le theko: lipalo tse bohlokoa
Lipalo tse peli li etsa qeto ea hore na mochini o lumellana le khoebo ea hau - 'me ka bobeli ho bonolo ho sebetsa pele o reka.
Mohlala - 5 L can ka potoloho ea 7.2 s, hlooho e le 'ngoe:
(3600 ÷ 7.2) × 0,8 =400 makotikoti/h· lichifi tse peli ≈6,400/letsatsi
Resin = karolo ea boima × theko ea resin → mohlala. 0,20 lik'hilograma × $ 1,30 =$0.26
Matla = mochini kW × $/kWh ÷ likarolo/h → mohlala. 15 × 0,12 ÷ 400 =$0.0045
Hlokomela hore resin e fokotsa matla le mosebetsi ka theko e 'ngoe le e 'ngoe. Taba ena e le 'ngoe ke taba ea taolo e nepahetseng ea botenya ba lebota: ho fokotsa 5% ea resin ho tsoa karolong eo likepe tse limilione li e bolokang ho feta tefiso efe kapa efe ea motlakase - ke ka lebaka leo mochini o theko e tlase o nang le taolo e fokolang ea lebota hangata o fetohang o theko e boima.
Re u thusa joang ho khetha
Ha moreki a romela potso, re sebetsa ka karolo, eseng mochini. Araba tsena mme tlhophiso e nepahetseng hangata e hlakile:
- Karolo e kholo ka ho fetisisa le sebopeho.Boholo le hore na e na le molamu etsa qeto ea extrusion vs ente, le e tsoelang pele vs accumulator.
- Resin le litšoaneleho tsa lebota.Barriers kapa regrind layers hloka hlooho ea multilayer; Meropa e lekantsoeng ka UN e hloka taolo e matla ea botenya ba lebota.
- Tlhahiso ea letsatsi le letsatsi.Etsa lipalo tsa lipalo khahlanong le lihora tse peli tse fetohang pele u khetha seteishene se le seng vs habeli.
- Setifikeiti.Liteko tsa ho theoha kapa litlhoko tsa UN li fetola lisebelisoa le netefatso.
- E ikemetseng kapa turnkey.Mehala ea ho lekanya e rua molemo ho fepelong e bohareng, metsi le ho sila ho fanoa hammoho.
Boleng, tlhahlobo le seo re se shebellang
Consistency ke papali eohle ea ho bopa, 'me ke moo lilemo tse mashome a mabeli tsa ho haha mechini e tšoanang li hlahang. Lintho tse seng kae tseo re li etsang le ho li shebella:
