Dhinaca dib-u-warshadaynta caagga ah, si loo sii wado tayada sareeysa ee alaabta dib loo warshadeeyay, PET alaabta dib loo warshadeeyay waxay u baahan tahay in la cusboonaysiiyo oo la gaarsiiyo heer u dhigma waxqabadka PET ceeriin. Ka mid ah caagadaha kala duwan, polyetylen terephthalate (PET) ayaa si weyn loogu isticmaalaa goobta baakadaha, gaar ahaan taagan baakadaha cabitaanka dhalada ah. Si kastaba ha ahaatee, si loo wanaajiyo waxqabadka PET alaabta dib loo warshadeeyay lana gaarsiiyo heer u dhigma tan PET-ga, tignoolajiyada horumarsan ayaa loo baahan yahay, taas oo ah PET IV mashiinada kordhinta viscosity.

Qiimaha IV waa halbeeg muhiim ah oo lagu cabbirayo cufka molecular ee PET, taas oo ka tarjumaysa dhererka silsiladda polymer-ka oo si toos ah ula xidhiidha sifooyinka farsamada sida xoogga, adkaanta, iyo socodsiinta. Native PET caadi ahaan waxay leedahay qiime sare IV, sidaas darteed lahaansho adkeysi iyo daahfurnaan aad u fiican. Si kastaba ha ahaatee, inta lagu jiro habka dib-u-warshadaynta, qiimaha IV ee jajabyada PET ayaa badanaa hoos u dhacaya sababtoo ah kulaylka iyo burburka farsamaynta hore.
Mashiinka kordhinta IV waxaa loo isticmaalaa in lagu kordhiyo viscosity ee walxaha dib loo warshadeeyay, taasoo u ogolaanaysa walxaha PET ee dib loo warshadeeyay in dib loogu daro{0} alaab tayo sare leh.

Mashiinka dib-u-warshadaynta PET ee jajabka IV waa mashiinka dib-u-warshadaynta khaaska ah ee loo isticmaalo in lagu kordhiyo cufka molecular ee jajabyada dib loo warshadeeyey ee PET. Farsamadani waxay caadi ahaan isticmaashaa habka adag -State polymerization (SSP), kaas oo PET flakes dib loo warshadeeyay lagu kululeeyo meel ka hoosaysa barta dhalaalaysa ee jawiga kontoroolka ah (sida caadiga ah nitrogen ama faakuum) si kor loogu qaado fidinta ama isku darka silsiladaha polymerka iyada oo aan dhalaalin jajabka.
Habkani wuxuu caawiyaa in la dayactiro dhaawaca silsiladaha polymer ee ku ururay marxaladihii hore ee habaynta iyada oo la saarayo wax soo saar aan kacsanayn iyo gaarista falcelinta silsiladda ee dib u dhiska cufka kelli. Sidaa darteed, jajabyada PET ee dib loo warshadeeyay waxay leeyihiin IV sare, crystallinity wanaagsan, iyo sifooyin farsamo oo wanaagsan.

1. Hagaajinta tayada alaabta
Kordhinta PET flakes dib loo warshadeeyay waxay wanaajin kartaa awooda farsamada, xasiloonida kulaylka, iyo hufnaanta PET dib loo warshadeeyay, taasoo ka dhigaysa mid ku haboon codsiyada dalabaadka sida dhalooyinka heerka cuntada iyo baakadaha warshadaha.
2. Saamaynta deegaanka
Marka la wanaajiyo tayada xaashida PET ee dib loo warshadeeyay, ku tiirsanaanta PET ceyriin waa la dhimay, waxaa la badbaadiyay kheyraadka fosil, iyo qiiqa gaaska aqalka dhirta lagu sii daayo ee la xiriira wax soo saarka caagga cusub ayaa hoos loo dhigay.
3. Qiimaha dhaqaale ee sarreeya
Qalabka PET ee dib loo warshadeeyay ee IV-ga sare leh waxay heli karaan sicirka suuqa oo wanaagsan waxayna furaan suuqyo faa'iido badan, sida warshadaynta fiber polyester-ka iyo qaabaynta duritaanka, taasoo kordhinaysa faa'iidada tas-hiilaadka dib-u-warshadaynta.

Iyadoo ay horseedayaan horumar waara iyo cadaadis sharciyeed, warshadaha dib-u-warshadaynta PET ayaa si degdeg ah u koraya. Isku dhafka IV ee kordhaya iyo burburinta, nadiifinta, iyo khadadka wax soo saarka granulation ee PET hal xariiq si loo dhimo qiimaha alaabta ceeriin PET, wanaajiso tayada alaabta PET ee dib loo warshadeeyay, iyo dardargelinta u gudubka dhaqaalaha balaastiga wareegtada ah.
Mashiinka kordhinta ee PET flakes IV waa horumarka muhiimka ah ee warshadaha dib u warshadaynta PET. Dib u soo celinta polymers-ka xumaaday ee u dhow tayadoodii asalka ahayd, waxay awood u siinaysaa wax-soo-saarayaasha inay soo saaraan badeecooyin caag ah oo waara iyagoon wax u dhimayn waxqabadka. Iyada oo ay kor u kacday baahida caalamiga ah ee PET dib loo warshadeeyay, maalgelinta tignoolajiyada sii kordheysa ee IV ma aha oo kaliya tallaabo caqli-gal ah, laakiin sidoo kale muhiim u ah dhisidda mustaqbal cagaaran oo wareeg ah.
