Mutane da yawa daga cikin abokan ciniki ta hanyar gidan yanar gizon mu suna ba da shawara ta waya kan shaharar nau'ikan jakunkunan saka, sannan a yau jakar saka ta DongLai Xiaobian don bayyana shaharar nau'ikan jakunkunan saka.
Nau'ikan jakunkunan saka
Jakunkunan da aka saka kuma ana kiransu da jakunkunan fata na maciji. Wani nau'in filastik ne, wanda galibi ake amfani da shi don marufi. Kayan da aka saka galibi sune polyethylene, polypropylene da sauran kayan filastik na sinadarai. Ga ɗan gajeren bayani game da nau'in jakar da aka saka da amfaninta.
Polyethylene shine babban kayan da ake samarwa a ƙasashen waje, polypropylene shine babban samfurin gida. Resin thermoplastic ne wanda aka yi ta hanyar polymerization na ethylene. A cikin masana'antu, ya haɗa da copolymers na ethylene tare da ƙaramin adadin α-olefin. Polyethylene ba shi da wari, ba shi da guba, yana da kakin zuma, yana da juriya mai kyau ga ƙarancin zafin jiki (mafi ƙarancin zafin aiki har zuwa -70 ~ -100 ℃), kyakkyawan kwanciyar hankali na sinadarai, yawancin juriyar lalata acid da alkali (juriyar acid, oxidation), ba ya narkewa a cikin abubuwan narkewa gabaɗaya a zafin ɗaki, ƙarancin shan ruwa, kyakkyawan aikin kariya na lantarki; Duk da haka, polyethylene yana da matukar damuwa ga matsin lamba na muhalli (tasirin sinadarai da na inji) kuma yana da ƙarancin juriya ga tsufan zafi. Abubuwan da polyethylene ke da shi sun bambanta daga iri zuwa iri, galibi ya danganta da tsarin kwayoyin halitta da yawa. Hanyoyin samarwa daban-daban na iya samar da yawa daban-daban (0.91-0.96g/cm3). Ana iya sarrafa polyethylene ta hanyar da ake ƙera filastik na thermoplastic na yau da kullun (duba sarrafa filastik). Ana amfani da shi sosai wajen samar da fim, kwantena, bututun mai, waya ɗaya, waya da kebul, kayan yau da kullun, da sauransu. Ana iya amfani da shi azaman kayan kariya mai yawan mita ga TV, radar, da sauransu. Tare da ci gaban masana'antar mai, samar da polyethylene ya bunƙasa cikin sauri, wanda ya kai kusan kashi 1/4 na jimlar samar da filastik. A shekarar 1983, jimillar ƙarfin samar da polyethylene a duniya shine tan 24.65, kuma masana'antar da ake ginawa tana da ƙarfin tan 3.16.
Polypropylene (PP)
Resin thermoplastic da aka yi ta hanyar polymerization na propylene. Akwai nau'ikan tsari guda uku, wato, cikakken isotopic, atactic da kuma kai tsaye. Kayayyakin masana'antu galibi sun ƙunshi tsarin isotopic. Polypropylene kuma ya haɗa da copolymer na propylene da ƙaramin adadin ethylene. Yawanci yana da haske, mai ƙarfi mara launi, mara ƙamshi kuma ba ya da guba. Saboda ƙa'idodin tsarinsa, yawan lu'ulu'u, wurin narkewa har zuwa 167 ℃, juriyar zafi. Tare da yawan 0.90g/cm3, shine filastik mafi sauƙi. Juriyar tsatsa, ƙarfin tensile 30MPa, ƙarfi, tauri da bayyanawa sun fi polyethylene kyau. Rashin kyawun shine juriyar tasirin zafi mara kyau, yana da sauƙin tsufa, amma ana iya gyara shi kuma a ƙara shi don shawo kan sa.
Launin jakar da aka saka fari ne ko fari gabaɗaya, ba shi da guba kuma ba shi da ɗanɗano, illar da ke tattare da jikin ɗan adam gabaɗaya ƙanƙanta ce. Duk da cewa an yi ta ne da nau'ikan robobi masu sinadarai, amma kuma yana da ƙarfi wajen kare muhalli, kuma ƙarfin sake amfani da shi;
Ana amfani da jakar saka sosai, galibi ana amfani da ita wajen marufi iri-iri na kayayyaki, kuma ana amfani da ita sosai a masana'antu;
Jakar da aka saka ta filastik mai resin polypropylene a matsayin babban kayan da aka saka, ana fitar da ita zuwa zare mai faɗi, sannan a saka ta a cikin jaka.
Jakar filastik mai haɗaka da aka saka da yadi mai filastik a matsayin kayan tushe, ta hanyar ƙera shi.
Ana amfani da shi wajen tattara foda ko kayan da aka yi da granular da kuma kayan da aka sassauƙa. Jakar da aka saka ta filastik mai hade-hade ana raba ta gida biyu a cikin jaka ɗaya da uku a cikin jaka ɗaya bisa ga babban abun da aka haɗa.
Dangane da hanyar dinki, ana iya raba ta zuwa jakar dinki ta ƙasa, jakar dinki ta ƙasa, jakar sakawa da jakar dinki mai manne.
Dangane da fa'idar jakar, za a iya raba ta zuwa 450, 500, 550, 600, 650 da 700 mm. Dole ne ɓangarorin biyu su amince da takamaiman bayanai.
A sama akwai shaharar ƙananan kayan shafa ga duk nau'ikan shawarwari masu alaƙa da jaka da aka saka, ta hanyar raba abubuwan da ke ciki, zuwa ga yaɗuwar nau'ikan jaka da aka saka suna da wasu fahimi, idan kuna son zurfafa cikin jakar bayanai ta kasuwa, za ku iya tuntuɓar mai siyarwa a kamfaninmu, ko kuma zuwa gabas da binciken jaka a wurin, an tattauna sadarwa ta juna a cikin wannan takarda.
