Sei kusarudza guruu kuti polyethylene: mazano uye wongororo

Polyethylene - ndeimwe dzakakurumbira uye vanozivikanwa zvinhu. Kunyanya kudhura uye, vose zvavo, vane mwero. Polyethylene rinowanzoshandiswa kuvaka greenhouses uye greenhouses kuti kuputira uye nyorova-proofing zvinhu zvakasiyana-siyana. Panguva basa vatenzi zhinji vakasangana pamwe kudikanwa micheto yekapepa katsva aka acho. Ndiyo apo matambudziko kutanga. Chokwadi kuti polyethylene ndiye havaratidzi kubatana. Asi murichengete achiri zvinobvira tichibatsirwa guruu. Zvinogonekawo kuti pasi zvinoitwa kupisa. Sei kusarudza zvakanaka namira nokuda polyethylene uye kuti zvakakosha kuteerera kubasa? Mhinduro dzemibvunzo iyi nemimwe anogona kuwanikwa pazasi.

ehupfumi kuti polyethylene

zvinhu zvinoshamisa Izvi zvinofadza ehupfumi zhinji. Polyethylene inoshandiswa kudzivirira mwando ndiyo yakanaka zvemagetsi insulator uye anokwanisa rokutora mumwe kupfuura ngozi siyana nemwaranzi. Zviri zvinenge chose nemishonga makemikari. It ndirwo okupedzisira dzimwe nguva chiremerera ichichinja kuvamirira. Chisimbiso zvinhu zvakadaro uye sei kusarudza namira polyethylene?

Sezvineiwo, chokuedza - haisi chete makemikari, asi kune vamwe zvakadini magetsi muitiro. Molecules chokuita zvinhu zviri vakwezvane nokuda musiyano pamabasa avo. Saka zviri zvakaoma kuwana fuma kuti inoomerera zvakanaka polyethylene kwakanga, uye pashure vachiyanikira anobata zvakasimba pamwe waakaita zvidimbu. Sezvo mamorekuru kwemashoko ari chaizvo "mwero", zvino micheto yekapepa katsva aka zvinogona kwazvo kwakaoma nevamwe zvinhu. Kunyange zvakadaro, makemikari indasitiri akaita guruu nokuda kwokuva polyethylene. Uye kwete mumwe. namira kwakadaro kunofanira nhaka zvimwe zvivako. Ngatitarisei kuti chii.

Zvinodiwa kuti namira zvinhu

Kana ukasarudza kuomerera polyethylene kana penofenol (mutsa furo) kuti kongiri kana chidhinha Nechepamusoro, fastening namira rukoko vanofanira zvinoverengeka zvivako:

• Ramba kugadzikana kuti zvinokonzerwa weathering.
• Regai kuparadza abraded zvinhu.
• Iva yakakwirira mwero hygroscopicity uye adhesion.
• Iva husingakwanisi tembiricha yakaderera.
• Iva akambozvishandisa kuuraya utachiona uye fungistatisticheskie unhu.
• Kuchengetedza zvivako zvavo kwenguva refu.

Consumer ongororo vanoti kuti kuri zviripo anoteerera nezvakatipoteredza kuchengeteka namira. Izvi zvinonyanya kukosha kana uchishandisa zvokuvakisa zvokunyaradza kushongedzwa. Kana ukasarudza kushandisa polyethylene (penofenol) pakuberekwa kutsva saunas kana dzokugezera, tinofanira kuteerera mamwe kupisa nemishonga namira uye kurwisa kwayo mvura inopisa mhute.

Sei kusarudza guruu?

Kana usingazive kuti namira polyethylene mhando zvakakunakira, kumbira mutengesi kutsvaka mumwe rinosanganisira methyl acrylate. Izvi zvinhu rinopa nokukurumidza kunyoroveswa polyethylene uye yepamusoro chokuedza. Uyewo nzira zvingasanganisira chromic anhydride, acids siyana uye xylene. The chisingarambiki mukana namira uyu paunenge kuishandisa haudi okuwedzera pamusoro kurapwa. Asi vanozvishandisa vanoti ane pakakanganisika. polyethylene namira kwakadaro muchetura chaizvo. Saka, zvose zviri basa riri zvakanakisisa panze. Eya, kana kuti kupa unhu kufefetedza. Zvakanakisisa micheto yekapepa katsva aka "mabasa" pane imwe tembiricha kuti +35 C. Haasi kutya mwando, asi ari nyore dzakaparira.

Uyewo muzvitoro panowanikwa nzira unobva Polymers. Ivo vanotengeswa muchimiro gobvu namatidza. Ava vaisanganisira solvent kazhinji chaidzo. Pashure maererano maviri zvinoriumba, asi namira anowana zvinodiwa mamiriro. Sezvo solvent runopwa nokukurumidza, shandisa musanganiswa kubatsirwa nokukurumidza. Saka regai chete kubereka zvakawanda.

Asi neoprene namira nokuda polyethylene zviri nani kwete kushandisa. sezvamunoita yakadaro yakakodzera kuti unobva rabha kana rubberized zvikamu neoprene jira, dehwe, akanzwa, zvedongo, simbi, chero mubatanidzwa. Asi nokuda polystyrene, rakawedzerwa polypropylene, polyethylene, uye plasticized PVC zviri nani kwete kushandisa. Hapana vachadaro.

Acrylic namira chete filler

Kana usingazivi chii kuti micheto yekapepa katsva aka polyethylene furo, edza kushandisa miviri-chezvinonhuwira pahwaro chete methyl. Nerumwe, unogona kuedza Easy-Mix Pe-PP Brand Weicon. Rine kwazvo adhesion ehupfumi. Rinoshandiswa nokuda kwokuva polypropylene, polyvinylchloride nezvimwe polymeric zvinhu. Kana kushanda namira ichi achafanira kukurumidza. It anoramba ehupfumi ayo pachena mhepo haasi maminitsi anopfuura matatu.

Easy-Mix Pe-PP ine chirungiso zvinosanganisira nemaziso magirazi marozari. filler Izvi hazvirevi ibvapo yacho guruu chisungo. Naizvozvo, kuti musono rinozobudawo simba zvakakwana. namira kwakadaro nokuti polyethylene furo rinofanira kushandiswa chete kubva pakutanga kavha yacho chisanganiso. Kushanda naye chaizvo ari kudziya +22 ° C. Full nokuomesa kunosimbiswa kwete kwokutanga pane maawa 5-6.

epoxy namira

Chokwadi, hakusi akakodzera chaizvo namira nokuda kwokuva polyethylene. Asi kana iwe usingagoni kuwana chimwe chinhu, unogona kuedza. Just kutanga kugadzirira pamusoro:

1. Micheto of waakaita zvikamu "kuchenesa" yakanaka Emery jira. Zvadaro kwazvo degrease navo.
2. zvikamu zvose muitiro ane 20% mhinduro kubva chromic anhydride kana 25% mhinduro kuti potassium dichromate. Kana izvi kwaikwanisa haana kuwanikwa, unogona kushandisa simba mhinduro kuti potassium permanganate.
3. Pashure pamusoro kurapa rakaoma.
4. Sanganisa kuti namira maererano nemirayiridzo. Shandisa nhete rukoko pamusoro chokuedza hukawanika. Pakarepo Dock mashoko.
5. Mira kwemaawa anoverengeka, uye zuva nani - kuti apedzise solidification musono.

User ongororo dzinoratidza kuti phenol-formaldehyde nebwe ane wakanaka adhesion kuti polyethylene. Saka kana iwe kutevera kunyatsoongorora mirayiridzo, uchabudirira.

Kunamatira polyethylene: nokurairirwa

Sezvaunogona kuona, kuti micheto yekapepa katsva aka polyethylene, vamwe zivo inokosha haudi. The nzira inoshanda pakarepo akajairwa:

• kuchenesa;
• degrease
• akaoma;
• kuparadzira namira nziyo;
• chisimbiso zvikamu;
• dzvanya;
• siya kuti dziome zvachose.

Panguva iyoyowo, sezvawaizoita pamwe zvimwe zvine chepfu, vanofanira kuva nehanya pamberi anodzivirira magirazi, magiravhusi uye unomubatsira kufema.
