I. Iimpawu zentsebenzo ezibalaseleyo

1. Uzinzo oluphezulu

I-Pentaerythrit ineenjongo ezintle zekhemikhali. Phantsi kweemeko ezahlukeneyo zokusingqongileyo, unokugcina uzinzo lwesakhiwo sayo kwaye akakhethwanga ekuphenduleni kweekhemikhali, ukubonelela ngesiqinisekiso esithembekileyo sokusetyenziswa kwexesha elide. Nokuba kubushushu obuphezulu, ubushushu obuphezulu okanye i-acid-basensise, inokubamba umhlaba kwaye iqinisekise ukuba intsebenzo yemveliso ayichaphazeleki.

I-2. Umoya olungileyo

Ibonisa ukulima ngokugqwesileyo kwizinyibilikisi ezahlukeneyo zezinto eziphilayo. Olu phawu lwenza ukuba iPentaerrythritthritlil ixutywe kunye nezinye izinto zekhemikhali, ekuboneleleni ngokulungiselela ukumiselwa okwahlukeneyo. Nokuba kusentsini yemitya, imihlambi okanye iplastiki, inokuhlanganisa ngokulula kwinkqubo kwaye idlale indima yayo eyahlukileyo.

I-3. Iimpawu zeqela elisebenzayo

Imolekyuli yePentaerythritTrit iqulethe amaqela ama-Hydroxyl amane e-hydroxyl, ayoyinge ngokunyuka okuphezulu kunye nokuqalisa. La maqela e-hydroxyl akwazi ukusabela ngeendlela ezahlukeneyo kwaye afikelele kwimichiza yekhemikhali njengokuhlisha kunye nokwahlulahlula-ntetho, ngaloo ndlela ekuqulunqweni kweemveliso ezahlukeneyo zokuhlangabezana neemfuno ezahlukeneyo kumashishini ahlukeneyo.

II. Uluhlu olubanzi lwemihlaba yesicelo

1. Umncedisi onamandla kwishishini elikhanyayo

Kwingubo, iPentarirythrit, njengento ebalulekileyo yokwenza ifilimu, inokunyusa ubunzima, ubugqwetha kunye nokuqina kwengubo. Inokunxibelelana namacandelo anjenge-resins ukwenza ifilimu eqinileyo nefanelekileyo, ukukhusela ngokufanelekileyo umphezulu wento enomxholo kwaye kwangaxeshanye unika ukuphindezela impembelelo entle yokuhombisa. Nokuba yingubo yangaphakathi eludongeni okanye ingubo yangaphandle yentsimbi, iPentaerythrit inokuthintela iingenelo zayo kwaye yenza amachiza agqwesile ngakumbi.

I-Pentaerythrit ikwasetyenziselwa ukulungiswa kwengubo yanganamanzi. Ngeemfuno zoKhuselo lweNkcubeko yeNkcubeko yezeNdalo, imfuno yeMarike ye-Waternergys ikhula ngokuqhubekekayo. Kwingubo ye-Abterborne, inokuphucula uzinzo kunye nokusasazeka kwengubo yangaphantsi kwaye inciphise umxholo wezinto eziphilayo eziguqukayo

2. Isithako esiphambili kwintsimi ye-adhesive

I-Pentaerrythritol idlala indima ebalulekileyo ekunxibeleleni. Inokonyusa i-viscofity kunye namandla okubulala izibhengezo kunye nokuphucula ukunamathela kubambeko kwizinto ezahlukeneyo. Nokuba luphawu lwezixhobo ezinjengeenkuni, iphepha, iplasitiki okanye intsimbi, ixhomekeke kwintsebenzo egqwesileyo yePentaerythritthritthritthritthritthritthritthritthritthritthritthritthritthrit.

Kwizicelo ezithile ezikhethekileyo, ezinje ngokuhlala kwiindawo ezinobushushu obuphezulu, uzinzo oluphezulu kwePentaerythrit yenze ukuba igcinwe isebenza kakuhle kwiimeko zeqondo lokushisa eliphantsi kweqondo lokushisa eliphantsi kwemveliso.

I-3. I-ASTATION EBALULEKILEYO KWI-PRETTAPR

Njengomntu weplastiki, i-pentaerythrit iphucula intsebenzo yokuqhubela phambili kunye neempawu zomzimba zeplastiki. Inokongeza ukugcwala kweplastiki, ukwenza i-plastics zeplastiki igudileyo kwaye kuncitshiswe ubunzima kunye nokusetyenziswa kwamandla. Kwangelo xesha, inokuphucula amandla, ukuqina kunye nokuchasana nobushushu beplastiki kwaye kwandisa ubomi benkonzo yeemveliso zeplastiki.

Kumingeni lokuthintelwa kweeplasitiki eziphezulu, i-pentaerrythriol sisithako esibalulekileyo. Umzekelo, kubuchwephesha beeplanga zobunjineli njenge-polycarbonate, inokwenza ukuba i-molecular yendlela yeplastiki kunye nokuphucula ukusebenza kweplastiki, isebenzisa i-elektroniki, inqwelo moya, ukuhlangabezana neemfuno eziphezulu zezixhobo ezikule mimandla.

4. Isicelo esibanzi kwamanye amasimi

Kwintsimi yamayeza, i-pentaerrythrit inokusetyenziswa njengeliphakathi leSynthesis kwaye ithathe inxaxheba kwinkqubo yokulungiselela amachiza ahlukeneyo. Isakhiwo sayo sekhemikhali kunye nokukhusela ukubonelela ngezimvo ezintsha kunye neendlela zophando lweziyobisi kunye nophuhliso, ukunceda ukuphucula amachiza afanelekileyo nezikhuselekileyo.

Kwishishini lokutya, iPentaerythrit ivunyelwe ukuba isetyenziswe njengesongezo sokutya, ikakhulu ngokuhlengahlengisa i-acidity kunye nokugcinwa kokutya. Ingaphucula incasa kunye nokuthungwa kokutya kwaye yandisa ubomi bokutya. Inezicelo ezithile kukutya okuthile ezinje ngeeCapies kunye neziselo.

Ukongeza, iPentagerythritol ikwadlala indima ebalulekileyo kumashishini anjengeencwadi, ipepermang, kunye nee-inki. Kwishishini lendwangu, inokusetyenziselwa unyango lwefayibha ukuphucula ukusebenza kweentsinga; kwimveliso yepakethi, inokusetyenziswa njenge-arhente yomeleza iphepha ukuphucula amandla kunye nomgangatho wephepha; Kwishishini le-inki, inokuphucula ulwahlulo kunye nokomisa ipropathi ye-inki kunye nokuphucula umgangatho wokuprinta.
