Polyetylen Crosslinked: codsiga iyo sifooyinka

Polyetylen waa wax a in loo isticmaalaa in warshado kala duwan. Products ka ayaa sidoo kale loo isticmaalaa in nolol maalmeedka. polyetylen Common waligiiba xoog ilaa 130 digrii. Si kastaba ha ahaatee, waxaa inta badan loo baahan yahay in ay isticmaalaan qalab this, iyo in xaaladaha sii daran ee heerkul sare iyo cadaadiska, tusaale ahaan in nidaamka kuleylka iyo biyaha kulul.

baahida loo qabo Tani waxay keentay in raadinta siyaabo si ay u helaan wax ka badan waarta. technology helay awoodi polyetylen crosslinked, taas oo uu leeyahay miisaan weyn kelli sida wax caadiga ah marka la barbar dhigo, oo soo hagaagtay sifooyinka. By isku xidhka fahmaan habka by kaas oo isku xidha taagoo ay sabab u formation of cross-links ku xiran yihiin in shirokoyacheistuyu a Roobka saddex dhinac-cabbir ah.

Iyada oo ku xidhan saamaynta codsatay kala saaro kiimikada iyo crosslinking jirka. Xaalada danbe, beebka (cross-lala polyetylen waxaa loo isticmaalaa in la abuuro waxyaabaha of data) waa la gubaa leh X-rays adag. Technology Tani waa mid aad u soo saar leh, iyo in daqiiqad aad ka heli karto ilaa 80 mitir oo ka mid ah waxyaabaha.

khasaaro ka mid ah habka ay tahay in polyetylen ah crosslinked ayaa dhumucdiisuna sinnayn biibiilaha. In gudaha jirsado boqolkiiba ugu hooseeya ee u taagoo xarunta, iyo ka baxsan, on lid ku ah, ugu sarreeya. Iyadoo la raacayo, guryaha iyo alaabta ee bulk kala duwan. Natiijadu waxay tahay category a crosslinked polyetylen C (PEX).

Marka la isticmaalayo habka kiimikada ah in bedel lagu of atamka hydrogen ee u taagoo waxaa lagu isticmaali silane walax gaar ah. Iyadoo la raacayo, silane a crosslinked polyetylen. In saaridda of tubooyinka qubeyska iyada oo gaar ah la walax buuxiyey noqotay. Tani waxay u ogolaaneysaa in la sameeyo nidaamka crosslinking uniform oo ka mid ah meelaha gudaha iyo kuwa dibadda derbiyada biibiile lagu hafiyo. Technology Tani waxay suuro gelineysaa in ay helaan biibiile la boqolkiiba sare ee processing, iyo wax loo qoondeeyey PEX-B.

Waxaa jira hab ka mid ah ka baaraandegidda xag nitrogen polyetylen ah wax laga dheefayo waxaa loo qoondeeyey PEX-D. Si kastaba ha ahaatee, technology tani ma aha khuseyn awgeed tayada yar yahay.

Sidoo kale qabtaan peroxides cross-xiriirinaya. Xaaladdan oo kale, habka wax soo saarka ayaa ka kooban isku qasin oo ka mid ah waxaay sheegayaan iyo polyetylen, ka dibna gobolka dahab la shubay ah, oo hoos heerkulka sare polyetylen crosslinked PEX-A group helay.

qalabka soo shubmo (kooxo B, C) ee loo isticmaalo biyaha iyo kuleylka, si kastaba ha ahaatee, waxay leeyihiin xadad dhowr la xidhiidha qalleyf iyo waxyaabaha ductility.

The ugu guulaha badan yihiin tuubooyinka ee group A polyetylen sameeyey, waxay leeyihiin xoog daal sare, crack iska caabin ah, xasiloonida cabbir ah, dabacsanaanta, iyo dulqaadashada inay ka nixin.

Kululaynta tuubooyinka PEX si ballaaran loo isticmaalo shakhsi, rayidka iyo dhismaha warshadaha. Iyadoo ay kaalmo u fuliyaan Floor qaabka hiitarka iyo abuuro nidaam kululaynta dabaqa a.
